In a large bowl, mash beans until a coarse paste forms. Add rice, breadcrumbs, scallions, jalapeno, tomato, cilantro, eggs, 1/2 teaspoon salt, and 1/4 teaspoon pepper; gently fold to combine. Using a 1/3 cup measure as a guide, form into 10 patties.
In a large skillet, heat half the oil over medium-high; add half the patties and cook until browned and cooked through, about 3 minutes per side. Transfer to a wire rack and tent with foil. Repeat with remaining oil and patties. Serve burgers on buns with desired toppings.
