One of my favorite ways to make a taco pizza is to put seasoned beef on a bed of mozz over sauce (never tried mixing with hot sauce.....would be good i bet)
Then you cook it up. Next you sprinkle fresh chopped onion (or cook with pizza if preferred) grated cheddar cheese, shredded lettuce, crushed corn tortilla chips, fresh tomato & Black olives. Served with a side of salsa & sour cream. I have never had a complaint other than running out too soon or being a bit messy hehehe
