Ratatouille Skewers are a fun and colorful appetizer or side dish that is perfect for summer gatherings or barbecues. The vegetables are cut into bite-sized pieces and threaded onto skewers along with some fresh herbs. The skewers are then grilled until the vegetables are tender and slightly charred. Serve the ratatouille skewers with a side of tzatziki sauce for dipping. These skewers are not only delicious but also visually appealing.
