Black Bean Burger with Caramelized Onions and Chipotle Mayo

Black Bean Burger with Caramelized Onions and Avocado

Summer is almost over but I am resisting that fact by making a bunch of summery food. These black bean burgers are totally loaded with lots of add-ons: mashed avocado, chipotle mayo, tomato, melted cheddar, and crispy caramelized onions. The actual burger is mixed with sweet corn, rolled oats and spices. It’s super filling and loaded with protein. The burgers are a little bit delicate and they do best cooked over a hot saute pan. Everything came together really well and it turned out super tasty! You can always add whatever fixins you want. Some other options would be sprouts, feta cheese, sauteed mushrooms, pickles and lettuce.
