Preheat the oven to 350°F.
In a saucepan, over low heat, combine the enchilada sauce, tomato sauce and gravy, stirring occasionally.
While the sauce is heating, brown the ground beef in a large skillet. Drain, then stir in the onions and spices. Continue cooking until the onions begin to become translucent. While the meat is still hot, combine the meat with a can of refried beans.
Warm the tortilla in a pan or in the microwave so that they are pliable enough for folding.
Place 2 heaping tablespoons of the meat mixture on a tortilla, top with cheese, lettuce and tomatoes. Fold the tortilla and place it in a baking dish. Pour the sauce over the burritos and top with lots of cheese.
Bake, uncovered at 350°F for 20 minutes.
