3 small to medium zucchini or summer squash, trimmed and sliced thinly lengthwise (⅛-inch slices)
1 Tbs. olive oil
salt and freshly ground black pepper
½ c. pizza sauce (or 1 c. red pasta sauce, heated in a small pot on the stove until reduced to ½ c.)
optional toppings: chopped black olives, sun-dried tomatoes, pepperoni slices, red pepper flakes, chopped fresh basil or oregano
Preheat broiler or grill. Brush each zucchini slice with the olive oil and sprinkle with salt and pepper. Broil on a baking sheet or grill until softened, about 4 minutes, flipping once halfway through. Let cool until safe to handle. Spread each zucchini slice with pizza sauce and sprinkle with toppings of choice. Roll up the zucchini slices from end to end, securing with toothpicks, if desired.
Serve at room temperature or chilled.
