Heat oven to 375 degrees F. Unroll dough; separate into 8 triangles. Place in ungreased 9-inch square pan or 10-inch pie plate; press over bottom and up sides to form crust.

In 10-inch skillet, cook beef over medium heat 8 to 10 minutes, stirring occasionally, until thoroughly cooked; drain. Stir in salsa and taco seasoning mix; simmer 5 minutes. Spoon meat mixture in crust-lined pan; sprinkle with cheese.

Bake 20 to 25 minutes or until crust is deep golden brown and cheese is melted. Served topped with lettuce and tomato.
