TOAST THE BAGUETTE:
Preheat your oven broiler. Arrange the bread slices in an even layer on a baking sheet. Top each bread slice with 1 piece of cheese; broil 3 minutes or until the cheese melts and the bread is toasted. Remove the pan from the oven.
ASSEMBLE THE BRUSCHETTA:
Top each bread slice with about 1½ tablespoons of the peach salsa. Serve immediately.
