Place the black beans, corn, chipotle pepper, adobo sauce, cilantro, cottage cheese, onion, cumin and black pepper in food processor. Pulse several times until the ingredients are mixed, but not pureed. Place the bean mixture in a bowl and stir in the cooked brown rice and breadcrumbs. Form the mixture into 3-inch patties.
Heat the canola oil in a large non-stick skillet over medium-high heat. Add the patties and cook for 4 to 5 minutes per side, or until golden brown and crisp.
Serve plain, on a whole grain bun or on a tostada with the toppings of your choice.
