Preparation: Start by preheating your oven to 400 degrees F.

Meat Mixture: In a medium skillet, cook the ground beef and onions over medium-high heat. Ensure they're evenly browned and the onions are translucent. Drain any excess grease. Next, season with garlic, cumin, salt, and pepper. Introduce the green chilies and refried beans, blending until thoroughly mixed. Keep this mixture warm.

Sauce Creation: In a separate pan, mix the tomato sauce, no-bean chili, and enchilada sauce. Stir consistently on medium heat until combined and warm.

Assembly: Split the beef-bean mix into six equal portions. Lay out a tortilla and spoon one portion of the mixture onto the center. Add a sprinkle of cheese and lettuce. (Feel free to modify with other vegetables if you prefer). Fold the tortilla sides over the filling, ensuring it's tightly packed to avoid any spillage.

Dish Setup: Grease two 9x13 oven-safe dishes. Place the prepared burritos, seam side down. Pour your previously prepared sauce generously over the burritos, ensuring they're well-coated. Crown them with the remaining cheese.

Baking: Position your burritos in the oven and bake for about 15-20 minutes. Once done, the burritos should be thoroughly heated, and the cheese perfectly melted.

Final Touch: Embellish your burritos with additional lettuce, tomatoes, sour cream, and a sprinkle of dried chives. Alternatively, pick your favorite toppings.
