If your grill is full, or you don't want to light it up, just broil the bread in the oven instead. Before adding the cheese mixture, broil bread, cut sides up, 2 to 3 minutes or until golden brown. Spread with the cheese mixture, then broil 2 to 3 minutes longer until cheese is hot and melted.
Kids love cheesy bread, but if they don't care for olives and green chiles, leave them out and use plain cheese spread.
The toasted bread can be topped, covered and refrigerated for up to 2 hours before heating it on the grill.
