Greek shrimp canapes are a delicious and refreshing appetizer that combines the flavors of shrimp, feta cheese, and Mediterranean herbs. The shrimp are marinated in a mixture of olive oil, lemon juice, garlic, and oregano, then grilled to perfection. They are served on toasted baguette slices and topped with a creamy feta cheese spread. These canapes are perfect for entertaining or as a light and flavorful snack.
