Flour tortillas
Hamburger, browned & spiced with garlic, cumin, onion, chili powder
Guacamole
Chopped onions
Chopped tomatoes
Shredded cheese
Green chilis
Green chili sauce or red salsa (whichever you prefer)

Mashed avocados, mayonnaise, 1 tablespoon lemon juice, cayenne pepper, garlic - if it sits overnight, it has more flavor.

Put everything inside the tortilla except sauce (if you want). Put in microwave a few minutes to heat everything. Add sour cream last, and enjoy.
