Sardines Stuffed with Spinach or Swiss Chard and Grilled

These sardines have all the full flavor of plain grilled sardines, but they’re flavored with garlic and made more substantial with cooked spinach or Swiss chard. Guests love them because most of the bones have been taken out, making them easy to eat with knife and fork or to pick up with fingers. If you have a square grill basket—the kind that looks like two cake racks with handles—use it for these sardines to make them easier to turn over. Heat the basket over the coals for about 30 second
