Sardine Recipe #5: A Sardine Wrap. Make the wrap pictured above. If you're going gluten-free or low-carb, substitute the wrap with a big butter lettuce leaf, swiss chard, kale, or bok choy. Fill the wrap with spinach, tomatoes, mozzarella or feta cheese, and then dump the can of sardines on top so that the olive oil saturates the vegetables. For added calories, include a sliced avocado in the wrap.
