My big complaint with vegan burgers is the massive amount of soy that usually comes with them. Look- there are some good “burger” patties, but I prefer to eat fresh, whole foods whenever I can.

This burger is a honking Portobello mushroom, loaded up with rich and buttery peppers and onions, some beans with a hint of lime, heirloom tomato slices, and some banana peppers for a bit of tangy zing.

It is a delicious, filling, and healthy meal that doesn’t taste healthy. You won’t even notice the lack of meat or cheese – and trust me, cheese is one thing I am obsessed with (I often let people know that cheese is literally my best friend.)

Pro Tips:


-Season your Portobello well, and cook it a bit more slowly than you would a meat patty. By cooking it a little slower and lower, you can cook out a bit of the mushroom’s moisture- which will make it feel less “slimy” (which is the #1 complaint I hear from people eating mushroom-based burgers.) It will also add to the rich, meaty flavor.


-Let your mushrooms and onions cook slow and low as well. The flavor you’re adding from them is going to add to the meaty and buttery flavors in the burger, and rushing them won’t let them fully develop.
