PETA has assessed the vegan-friendliness of meal-delivery companies across the U.S., grading each one based on the availability of plant-based meals and the ease of use for vegan customers. The resulting letter grades run the gamut from “A,” for companies that offer only vegan meals, to “F,” for those that have failed to make any attempt to provide an animal-free option.

This ranking is dynamic and will change as we receive updates from companies or learn of new vegan options.

Note: Many companies rotate their menus, so meal selections may vary from those listed in this article.

Grade A: All-vegan companies

Veestro meals include scrumptious vegan entrées such as Enchilada Casserole, Chick’n Quesadilla, and Country Fried Chick’n. A PETA Business Friend, it also offers a 21-day kick-start program.

PETA Business Friend Boycemode is a convenient vegan meal delivery service focused on holistic health and nutrition that offers customizable plans and delivers to select locations in New Jersey and New York City. Its options include prepared meals such as pesto pasta and vegan mac, Garlixir cleanses, meal-replacement smoothies, and afternoon wellness tonics.

Food Nerd offers all-vegan meal plans, such as the Daily Work Package and the Vegan Gains 2X Package for people looking to bulk up. Food Nerd’s breakfast, lunch, and dinner options include Scrambled “Eggs” & Hash Browns, Black Bean Burgers, Sweet Potato Ranch Salad, Thai Grain Peanut Bowls, and more.

MamaSezz is available in the northeastern United States. Its meals include Gardener’s Pie and Lazy Lasagna. It also offers a kid-friendly menu with options such as Mac Attack Stack and Millie’s Chili. MamaSezz is also a PETA Business Friend.

VegReady healthy vegan meals arrive ready to eat—with no refrigeration, no prep, no cooking, and no heating needed. Every scrumptious option is packed with nutrients that your body needs and free of added sugar and preservatives that it doesn’t. And since the company is a PETA Business Friend, you’ll be supporting PETA’s vital work for animals with every meal. We’ll raise a fork to that!

PETA Business Friend Purple Carrot is another 100 percent vegan meal-delivery company, and it serves up ingredients to make delicious dishes such as Vegan Chick’n and Dumplings with Oyster Mushrooms and Green Beans and Chipotle Cauliflower Fajitas with Avocado and Black Bean Crema.

FoodFlo offers shipping to all of California, the metropolitan areas of Las Vegas and Reno in Nevada, and the metropolitan areas of Flagstaff, Phoenix, and Tucson in Arizona. Its vegan meals are packed with veggies and include Creamy Tomato Soup and Mixed Greens Pecan Salad.

22 Days Nutrition meals include Sesame Butternut Squash Rice and Smokey Rosemary White Beans. It also makes a line of Plant Power protein powders and bars. This company is famous for guiding Beyoncé and Jay-Z on a 22-day vegan challenge.

The Vegan Garden offers meal plans such as the Two Week Slim Down Package, the High Protein Health Kickstarter, and more, with tasty options including Mongolian “Chik’n” and Enchiladas De Colorado.

Vegin’ Out is available in Southern California only. These ready-to-eat meals include Jambalaya and Pesto Linguine with Butternut Squash. Bonus: Your order comes with soup and vegan cookies.

Kitchen Verde’s ready-to-eat meals include Pumpkin Spice Pancakes, a Chipotle Tofu Burrito Bowl, and a gluten-free Chipotle Tofu Burrito Bowl. This company is perfect for those sticking to whole-food, oil-free food. Kitchen Verde offers its service in upstate New York.

Grade B: These are the best of the not entirely vegan companies. They offer a user-friendly site for customers and a selection of vegan options.

Grade C: These companies have some delicious vegan meals but could up their game by making their vegan options easier to find and offering a wider selection.

PeachDish has a couple of vegan options, offering comfort food with a Southern flair such as a Chickpea & Sautéed Spinach “Omelet” with Stone-Ground Grits, Sprouted Legumes, and Sriracha. We hope to see even more creative creations to come!

Marley Spoon offers some vegan options, such as General Tso’s Tofu and Crispy Chickpeas & Tomatoes with Garlicky Grits, but you have to search pretty hard to find its vegan meals, and the vegan search filter doesn’t work perfectly. Pluses include availability through Amazon and service in Australia, Germany, and the Netherlands in addition to the U.S.

California Chef Services serves the Los Angeles area. Meals include Argentine Vegetables Chimichurri and Grilled Vegetable Enchiladas. Many of its meals would be vegan if it weren’t for the added cheese. We’re hoping for a vegan cheese option in the future.

Grade D: These companies may occasionally have a vegan item on their menus, but they have a long way to go to become truly vegan-friendly services.

HelloFresh offers a Seitan Sloppy Joe or Vegetarian Paella every once in while, but vegans will be disappointed by the limited options and the cheese or eggs in many of the meat-free options.

The Home Chef site will frustrate people searching for vegan meals, as you can’t exclude both meat and dairy “products” from your search preferences.

Grade F: These companies don’t offer vegan options, except the occasional accidental one.

Plated carries some menu items that could be easily veganized if made without cheese, but it offers no option for ordering meals without animal-derived ingredients.

Dinnerly is the most affordable, kid-friendly of the meal services on the list, but the weekly menus offer few (if any) vegan meals. This company would benefit from offering vegan meals, as nearly all families have a vegan or vegetarian in the mix these days.

Grade Deferred

Meat-free favorite Beyond Meat’s Beyond Burger will be offered in Blue Apron subscriptions. However, the meal service doesn’t offer a vegan meal plan or a custom way to make your boxes vegan. Until it does, its grade is deferred.

Has one of your favorite meal-kit services received a failing grade? Contact it through its website, Facebook, Twitter, or other social media accounts to let it know that you want it to introduce vegan options—and encourage your friends to do the same.
