Preheat the oven to 375 degrees. Line a baking sheet with tin foil then place two wire cooling racks in the baking sheet (this helps the food cook on both sides evenly without flipping them while they bake). Spray with cooking spray.
Spoon some refried beans down the center of the flour tortilla then top with some shredded cheese. Roll into a burrito, making sure to fold in both sides to contain ingredients. Place on the cooling racks in the baking sheet.
Put into the oven and bake for 20-25 minutes or until golden brown. Side Note: If you don't use the cooling racks in your baking sheet make sure to flip the chimichangas halfway through cooking time. Serve immediately. Enjoy.
