In a food processor, puree 1 ½ cups of the black beans. If you don’t have a food processor, you can just mash them with a potato masher or wooden spoon. Place pureed black beans in a large mixing bowl, add the remaining ½ cup of whole beans and set aside.
Mince onions, garlic, and jalapeño pepper; add to black beans. Add the corn and mix.
Whisk together the egg white, tomato paste and all of the spices. This will make a thick paste. Add this to the bean/corn mixture.
Finally, add the breadcrumbs to the mixture. Mix together thoroughly until ingredients are combined. Mixture may seem dry but it should come together with mixing. If needed, add a second egg white.
Form mixture into patties (4 large patties or 6 medium patties). Place patties on a baking sheet and bake in a 375° oven for 8-10 minutes, flip the burgers, then cook for an additional 8-10 minutes.
