This after-school snack is inspired by nachos, but it's a bit healthier.
Heat broiler, with rack set in top third of oven. Arrange pita pieces in a single layer, cut side up, on a baking sheet; dividing evenly, top each first with salsa, then cheese.
Broil until cheese has melted and edges of pita are crisp, 2 to 4 minutes. Serve with extra salsa, if desired.
