1. Using a food processor, mix the red pepper. On a flat surface, using your hands, combine your red pepper mixture well into the ground beef. Using the food processor, mix the remaining onion, garlic, and green pepper. On a flat surface, using your hands, combine your onion, garlic, and green pepper mixture well into the ground beef. Add paprika until you achieve a reddish golden color. The color may be more golden. Add about a cup of flour to the ground beef, combining well. Open a hole within the ground beef mixture and fill with corn oil. Continue alternating between gradual addition of flour and corn oil until the ground beef mixture forms a solid dough, that when mixed does not stick to your hands.
2. Now, take your mixture and form round balls. You may make them to your desired size. Take your balls and flatten them into patties. You can make them as thick or thin as you like. Be sure not to make them too thin.
3. Spray a frying pan evenly all over with cooking spray. Turn on your stove to a moderate/high setting (about 7 or 8 on electric stove). Now you are ready to fry your fritas. You should make sure to turn them more or less constantly. Keep them cooking until they get a brownish color and a grilled well look.
4. Place each frita in a hamburger bun. If desired, the buns may be toasted first. Any toppings may be used for the fritas. Some suggestions are potato sticks, chopped onions, lettuce, tomato, or anything else you would normally put on a hamburger. Refrigerate unused portions storing on wax paper in a closed container. Separate each layer of fritas with a sheet of wax paper to prevent from sticking.
