Step 1

Place an oven rack on the highest position and preheat the broiler on high. Spray a baking sheet with non-stick cooking spray.

Step 2

In a large bowl, mash the beans with a fork or potato masher. Add the remaining ingredients and mix well with a fork or your hands. Shape into twelve patties and place on the baking sheet, working in batches if necessary. Brush both sides with olive oil. Broil for 3-4 minutes per side until crispy and cooked through.

Step 3

Serve with avocado, lime, sour cream, and salsa if desired.
