In a large bowl, mash the cannellini and black beans until smooth with some chunks. Add garlic, cilantro, paprika, onion powder, salt, and pepper and stir to combine.

In a small bowl, combine egg, egg white, 1 Tbsp. olive oil, and panko bread crumbs. Stir into bean mixture until well combined.

With your hands, form mixture into six patties.

In a large non-stick skillet, heat 1 Tbsp. olive oil over medium-high heat. Add patties and cook 4-5 minutes per side or until browned.

Meanwhile, make the chipotle mayo: using an immersion blender, combine all ingredients.

Assemble burgers topped with lettuce/spring mix and chipotle mayo.
