Start by preheating your oven to 375°F so it's fully heated by the time your burritos are ready to go in. I always do this step first so I'm not standing around waiting later. A properly preheated oven is what gives the tortillas that light crisp instead of a soggy texture.
In a large bowl, stir together the refried beans, cooked rice, 1 cup of the shredded cheese, salsa, chili powder, and cumin. I mix until everything is evenly coated and no dry pockets of rice remain. This filling doubles easily if I'm feeding a bigger crowd or want extras for the freezer.
Line a baking sheet with aluminum foil and spray it generously with olive oil cooking spray. This little step saves me from scrubbing burnt cheese off the pan later. It also helps the bottoms of the burritos crisp up nicely as they bake.
Spoon about ¼ cup of the bean and rice mixture onto the center of each tortilla. Fold in the ends, then roll it up tightly into a burrito shape. I place each one seam-side down on the baking sheet so they hold their shape while baking.
Spray the tops of the burritos lightly with olive oil, then sprinkle the remaining 1 cup of cheese over the top. Bake for 15 minutes, or until the burritos are heated through and the cheese has fully melted. If you like a toasted top, broil for the final minute while watching closely.
Pull the burritos from the oven and let them sit for a minute or two before serving. I like to plate mine over shredded lettuce with guacamole and pico de gallo on the side. This resting step keeps the filling from spilling out the moment you slice into one.
