Grilled Zucchini Rollatini are the perfect finger food for a picnic or outdoor soiree! Zucchini is sliced thin and grilled after being brushed with olive oil and seasoned with salt and pepper. Once grilled, the zucchini is chilled. Brush on basil-seasoned ricotta cheese with tomatoes, then roll the zucchini up into bite-sized pieces. Chill until it's time to eat, then enjoy. These Grilled Zucchini Rollatini make for a scrumptious summertime vegetarian appetizer or entree!
