We’ve been hooked on baby bella crimini mushrooms, but the other day, I decided to mix things up and get the portobello caps. As you probably know, portobellos make a great burger substitute, because you can grill ’em whole just like a steak, so I knew I wanted to make some kind of sandwich with them.

Portobello mushroom sandwiches have been done to death on food blogs, so I tried to come up with something that would make this one special: enter avocado aioli. Avocado aioli is basically like guacamole on steroids. This sandwich would have been good without it, but it was great with it.

We ate the sandwiches with some sliced pickles and grilled veggies on the side, along with an ice cold beer. I couldn’t be any happier with how they came out. I hope you give them a try and enjoy them as much as we did!

BTW, did you know some steak sauces are vegan friendly? It may seem a bit ironic, but it’s true. We used A. 1. Sauce for this recipe, but plenty others are also animal-free. Just be sure to check the ingredients label before you buy.
