Prep Pointer: Vertically sliced onions (as opposed to rings) separate nicely and meld better with the pasta.
Serve with Olive Flatbread: Preheat oven to 450°. Unroll 1 (11-ounce) can refrigerated thin-crust pizza dough onto a baking sheet. Combine 1½ tablespoons olive oil, ½ teaspoon crushed red pepper, and 1 minced garlic clove; brush over dough. Sprinkle dough with ⅓ cup chopped kala-mata olives. Bake at 450° for 11 minutes or until browned and done. Top with 2 tablespoons thinly sliced basil.
