For the cilantro crema, in a food processor or blender, combine all the ingredients except for salt. Process until smooth and creamy. Transfer to a small bowl, season with salt and mix well with a spoon. Taste and adjust seasoning. Transfer to an airtight container and keep in the fridge until ready to use.
Cook the tater tots until golden and crispy in toaster oven, air fryer, or deep fryer following the instructions from the package. It took about 25 minutes for mine to cook in a toaster oven.
While the tots are cooking, prepare the bacon. Line a rimmed baking sheet with aluminum foil. Lay the bacon on a single layer with 1-inch space in between. In a cold oven (no preheating), place the baking sheet in the oven. Set the temperature to 425˚F (220˚C) and cook until deep golden brown and crispy, about 20 - 25 minutes. Transfer to a plate lined with paper towels.
In a medium skillet over medium heat, warm 1 tablespoon unsalted butter. Add 2 eggs first and add them very close to each other. Then add 2 more eggs close to each other onto the other side of the skillet. Turn the heat down to medium-low. Cook the eggs until the egg white are set and not fully cook. Carefully insert a flat spatula under the first set of 2 eggs, then flip. Now, flip the other set. Cook for 30 more seconds and remove from skillet.
Wrap 2 tortillas with a large damp clean towel or paper towel. Microwave for 20 seconds. That will help the tortilla to be a little more flexible.
To assemble, on a clean working surface, place 2 tortillas side by side. On one tortilla, slightly spread out ¼ cup of cheddar cheese in the center. Sprinkle 1½ tablespoons cotija cheese over. Place 9 tater tots on the cheeses. Line the avocado wedges lengthwise on top of the cheeses and next to tots. Add 2 slices of bacon on top of the avocado. Add one set of 2 eggs on top of the tater tots. Keep all the ingredients tight and compact together. Fold the bottom part of the tortilla over the filling, then fold the left side and the right side to the center. Last, roll the burrito up tightly and carefully. Repeat with the other tortilla.
In a large skillet over medium heat, melt 1 tablespoon butter. Add the burritos fold side down and cook until golden brown. Carefully flip over and cook until golden brown. Transfer to a clean chopping board. Using a sharp knife, cut the burritos in half. Serve immediately with salsa de molcajete (or your favorite salsa) and cilantro crema.
