This tasty vegetarian starter is traditionally made with fresh zucchini, though my mom uses pumpkin in its place. Other alternatives like squash or other gourds and even cucumber can be used. Kolokythokeftedes are best served in the summertime during an early evening happy hour with a glass of Ouzo on ice. I’m already daydreaming of relaxing at a taverna on the Greek coast, sampling some pumpkin fritters and seafood mezze. Oh, the good life!
