Greek salad skewers are a fun and creative way to enjoy the classic flavors of a Greek salad. Chop cucumbers, cherry tomatoes, red onions, and feta cheese into bite-sized pieces. Thread the ingredients onto skewers, alternating between the vegetables and cheese. Drizzle the skewers with olive oil, lemon juice, dried oregano, salt, and pepper. Serve the skewers as a refreshing and healthy appetizer or as a side dish to accompany grilled meats or seafood.
