Heat large non-stick frying pan to med-high, melting the butter
Add the tater tots and fry until you can start breaking them up (I use a lid to speed things up). Add the sausage, breaking it up into the pan. Reduce heat to medium.
Add the finely chopped onion and the chilis. Stir frequently for about 4-5 minutes.
Stir until tots are broken up and browning and the sausage is JUST getting done. Add all the eggs into the mix and stir until they are all done. (You can stir the eggs all up in a bowl if you want to but I just break them all into the mix and keep stirring.)Season to taste. Do NOT turn stove off - just turn it down a little more.
Place tortillas on dinner plates. Sprinkle about 1/4 cup of cheese into middle of each one. Divide the fried mixture into 4 portions into middle of tortilla. Fold the tortilla sides in (like building an envelope) then fold the bottom up, rolling the burrito.
With the pan still on a low medium to medium setting, place each burrito back into pan, rolled edge down, and let them grill about 2-3 minutes on each side (keep an eye on them). If you have a weight to put on top of them that is great. I serve with pico de gallo or salsa and a fork. You won't be able to just pick these up! Garnish with some torn spring of cilantro.
