Preheat oven to 325 degrees F.
Cut bread into 1/4-inch round or oval slices and place on 1 large or 2 small baking sheets. Brush 1 side of each slice lightly with the olive oil, and lightly season with the salt and pepper. Bake until crisp and golden brown, 15 to 20 minutes. Remove from the oven and cool before serving.
Serve with dips of choice.
