Starting April 25th, you'll be able to get Del Taco's exclusive plant-based meat on just about any item on the chain's entire menu. This includes everything from the Beyond Taco and Beyond Avocado Taco to Loaded Queso Fries and secret menu items like the Bun Taco. Swapping out something like steak or regular ground beef for the Beyond Meat, however, will come at a slight upcharge.
