Place one tortilla (room temperature or warmed, see Notes) on flat work surface. Preheat oven to 400° Fahrenheit. Lightly grease baking sheet with spray oil and set aside.
Burritos with Meat & Eggs: Place shredded cheese across center of tortilla, being careful not to get too close to tortilla edges. Top cheese with layer of tater tots, then cooled egg mixture, then bacon or sausage. Sprinkle taco seasoning over filling to taste. Set aside and fill remaining tortillas.
Burritos with Tofu: Place shredded cheese, if using, across center of tortilla, being careful not to get too close to tortilla edges. Top cheese with layer of tater tots, then layer of cooled tofu mixture. Sprinkle taco seasoning over filling to taste. Set aside and fill remaining tortillas.
When all tortillas have been filled, roll burritos one-by-one and place seam-side down on baking sheet. See Notes for burrito-rolling tips. Repeat with remaining burritos.
When all burritos have been rolled, place filled baking sheet in preheated oven. Bake burritos 10 to 12 minutes, then remove baking sheet from oven and set aside to cool.
Once burritos have cooled completely, wrap each burrito securely in aluminum foil, making sure to fully cover both ends and all sides. Place foil-wrapped burritos on clean baking sheet in one even layer and place in freezer for 1 to 2 hours. Once burritos have frozen individually, transfer them to sealable freezer bag or other freezer-safe airtight container and freeze until ready to enjoy.
