This is a common Southwest/Tex-Mex breakfast recipe. But this version is a little different than the other recipes I've seen with the same title. So I thought I'd post it here for another option for anyone looking for a Tex-Mex breakfast idea.
Melt butter in a large skillet; cook onion, bell pepper, and mushrooms until tender.
Add the chilies, bacon, and egg mixture. Cook, stirring occasionally until eggs just start to set. Sprinkle cheddar cheese and Monterey Jack cheese over eggs. Cover, and continue to cook until eggs are set and fully cooked.
