Brown the ground beef in a skillet over medium heat.
Drain any excess grease.
Add taco seasoning and water to the beef.
Stir well and let it simmer for about 5 minutes.
Preheat your oven to 475 degrees Fahrenheit.
Place your pizza crust on a baking sheet.
Spread the seasoned beef evenly over the pizza crust.
Top it with shredded cheddar cheese.
Bake in the preheated oven for 8-10 minutes or until the cheese is melted and bubbly.
Once out of the oven, top the pizza with shredded lettuce, diced tomatoes, black olives, and any additional taco sauce if desired.
Slice and serve with dollops of sour cream on top.
