Make It Now:

1. Prep Beef Filling: In a large nonstick skillet, heat the oil over medium heat. Sauté the onion until it begins to soften, about 3-4 minutes. Add in the ground beef, cumin, and salt. Break up and cook the beef until it is no longer pink. Drain off the excess grease. 
2. Reduce the heat to low and stir in the corn, black beans, and salsa. Cook for 2-3 minutes, stirring occasionally. Set aside.
3. Preheat the oven to 400°F. Tear off 8 pieces of foil (big enough to wrap the burritos).
4. To fill each burrito, lay a tortilla out on a piece of foil and sprinkle about 2 tablespoons of shredded cheese over the tortilla. Then add 1/2 cup of beef mixture. (Optional: Add in cooked rice at this step.)
5. To wrap each burrito, fold in the sides of the tortilla over the filling. Then, fold the bottom up and roll the burrito tightly. Place the burrito seam down and wrap it tightly in the foil. (Freezing instructions begin here.)
6. Place burritos on a sheet pan (to catch any spills). Bake for 15 minutes or until heated through.

Freeze For Later: Place foil-wrapped (but not baked!) burritos into a gallon size freezer bag or container. Squeeze out any excess air, seal, label the bag, and freeze.

Prepare from Frozen: You have 2 options to heat the frozen burritos:

1) Microwave Method: Unwrap the foil from the frozen burrito, wrap in a moist paper towel, and microwave using the defrost setting for 2 to 3 minutes, or until warmed through.

2) Oven Method (Thawed): Thaw the burritos in the refrigerator. Bake as directed above.

Note: We have not tested warming these in the oven from frozen yet. However, you can try baking in the foil at 400°F for about 45 minutes or until warmed through. Let us know if you try this in the comments!
