For the garlic croustades, heat oven to 375 degrees. Cut a loaf of French bread into 3/8-inch diagonal slices and place on a baking sheet. In a skillet, over medium heat, combine 2 tablespoons each, olive oil and unsalted butter. Add 3 cloves garlic, minced, and a few dried hot red pepper flakes. Saute gently until garlic is softened, about 5 minutes. Brush some garlic mixture onto each bread slice in baking sheet. (If desired, sprinkle on some shredded Parmesan cheese.) Bake about 6 minutes, until lightly toasted. Serve warm.
