Roast the pepper over a gas flame or broil in the oven on a sheet pan lined with foil 4-inches from the top of the heating element, until charred and softened, turning the pepper as needed to sear each side, about 10 minutes.
Let the pepper cool; peel, seed, and chop. In a blender, puree the pepper with the feta, paprika and olive oil transfer to a bowl and refrigerate until ready to use.
Black Bean Quinoa Burgers
In a large bowl mash the black beans. Stir in the quinoa, bread crumbs, garlic powder, chili powder, cumin, paprika, salt, and pepper. Add the egg and mix well to moisten the ingredients.
Mix in the shredded cheddar cheese. Mix well again and form into 4 equal burger patties, flattened to about ¾-inch thick (about ¾ cup per patty). Transfer to a plate and refrigerate for at least 10 minutes.
In a large skillet, heat 1 tablespoon olive oil over medium heat. Cook one side of the patty for 5 minutes, until golden and crisp, flip and cook the other side for 5 minutes. Cover the pan with a lid and cook another 3 minutes to heat patty throughout.
Toast each bun and add 1-2 tablespoons of the red pepper spread to the bottom of each bun. Top with patty desired toppings and enjoy!
