First, prepare the marinade for the feta with extra virgin olive oil, lime, chopped mint or herbs, black pepper, and crushed garlic. Cut it into small pieces, cover it, and refrigerate for at least 30 minutes.
Meanwhile, pour the still-frozen zucchini into a pan, greased with a little oil, and cook for about 10 minutes, turning them a couple of times. Let them cool slightly.
In the meantime, microwave the Taggiasca olives on high for 5 minutes until they dry out. Once they are cool, you can crush them with your fingers
Finally, assemble the skewers by alternating marinated feta and zucchini, and refrigerate for 10 minutes. Serve with lime wedges, mint leaves, and a sprinkle of olive powder.
