1Using mandoline or sharp knife, cut 4 thin lengthwise slices from zucchini. (Refrigerate remaining zucchini for another use, or make additional roll-ups.)
2In small bowl, mix cheese, lemon peel, chopped basil, salt and pepper.
3Starting from short side, roll up each zucchini slice and secure with toothpick or skewer. Fill center of each roll-up with cheese mixture, using spoon or piping from plastic bag.
4Place roll-ups on small serving platter. Drizzle lightly with oil; garnish each with basil leaf. Sprinkle with additional pepper, if desired.
