Step 1

In a medium size mixing bowl, pour in your rinsed black beans and make sure they are as dry as possible. Mash your black beans with a fork.

Step 2

Next, add in the green chilis, grated onion, ketchup, bread crumbs, egg and the 4 spices. and stir until completely combined.

Step 3

Divide the mixture into fourths and form into thick patties. If you have trouble forming them, make them more into balls and then you can press them down in the skillet to form a patty. They will firm up once cooked.

Step 4

Place a non-stick skillet on medium heat with about 2 Tbsp butter or oil. Once melted, place your patties on the skillet and let cook for about 4 minutes or until the bottom has browned. Flip and cook the other side until browned. If you want the patties to be more firm, press down slightly on each patty with your spatula to get any extra moisture out and cook a little bit longer.

Step 5

For the sriracha mayo: mix mayo and sriracha. Begin with ¼ tsp sriracha and slowly add more according to taste.

Step 6

Garnish burgers and enjoy!
