Preheat oven to 350°F according to package instructions for the crescent rolls.

Gently unroll the crescent rolls onto a cookie sheet, pinching seams together to form a cohesive crust. Bake for about 12-15 minutes, or until golden brown, then allow to cool slightly.

In a skillet, brown the ground beef over medium heat, draining excess fat. Add taco seasoning and simmer for about 5 minutes.

In a bowl, combine softened cream cheese, sour cream, and your choice of salsa. Mix until smooth and creamy.

Spread the cream cheese mixture evenly over the cooled pizza crust. Layer on the cooked beef, diced tomatoes, shredded cheese, and finish with a sprinkle of lettuce.

Cut the pizza into squares and serve immediately.
