These Mediterranean chicken pinwheels are a delicious and healthy appetizer or snack. Thinly sliced chicken breast is marinated in a flavorful mixture of olive oil, lemon juice, garlic, and herbs, then rolled up with a filling of sun-dried tomatoes, feta cheese, and spinach. The pinwheels are then sliced into bite-sized pieces and served cold or at room temperature. These pinwheels are perfect for parties or for a quick and easy lunch.
