1/2 cup mayonnaise
2 teaspoons finely chopped chipotle pepper in adobo sauce (seeds removed for a milder mayo; leave them in for more heat)
1 teaspoon adobo sauce (from the can of chipotles)
1 small clove garlic, minced (about 1/2 teaspoon)
Pinch kosher salt
BLACK BEAN PATTIES:
1 (15-ounce) can black beans, drained and rinsed
1 egg (Leave out for Vegan)

1 small clove garlic, finely minced (about 1 teaspoon)
1 cup bread crumbs
2 teaspoons adobo sauce (from a can of chipotle peppers in adobo sauce)
1 teaspoon dried oregano
1/2 teaspoon cumin
1/4 teaspoon smoked paprika
1/8 teaspoon cayenne pepper (optional)
1/2 teaspoon kosher salt
1/8 teaspoon freshly ground black pepper
2 tablespoons olive oil
16 slider buns or rolls, sliced in half
8 ounces vegan pepper jack cheese, sliced thin
1/2 red onion, sliced
Sliced sweet pickles
Mix all ingredients together in a small bowl. Refrigerate in an airtight container until ready to use.
BLACK BEAN PATTIES:
Place beans in a small bow and mash with a fork or potato masher. Add egg, bread crumbs, adobo sauce, oregano, cumin, smoked paprika, cayenne (if using), salt and pepper. Mix well.
Form into one-ounce patties – about 2 tablespoons per patty – by rolling mixture into a ball, packing together firmly, then flattening slightly.
Add the olive oil to a large saute pan over medium heat. Working in batches so that the burgers aren’t too crowded, cook one one side until browned – about 5 minutes, then carefully flip and cook until browned and cooked through, about 10 minutes total.
Remove patties to a paper-towel-lined plate to drain and cool slightly.
Put slider buns sliced-side up on a cookie sheet. Add black bean patties to the bottom halves of the buns and top with cheese. Place under oven broiler until cheese has melted and buns are golden brown, about one minute (depending on your broiler – just watch carefully!)
Remove from oven and slather chipotle mayo on the inside of the bun tops. Top burgers with red onions and pickles, sandwich with the bun top, and secure with a toothpick or skewer. Serve immediately.
