To prepare Mexican rice, heat oil in a pan, then sauté onions and garlic. Add in tomato sauce, taco seasoning, and cumin powder. Stir to mix. Toss in rice and bell pepper until well blended. Season to taste. Continue cooking for another 3-5 minutes with continuous stirring. Set aside.
To assemble, lay one flour tortilla on a clean surface, then spoon in prepared rice, a small amount of chicken flakes, and a tablespoonful of refried beans and salsa, and then roll. Pan fry rolled burritos in a small amount of oil and brown on all sides.
