Grilled Tuna Rollatini under Tomato-Lemon Marinade

When traveling through Sicily, you will often encounter tuna or swordfish rollatini—or involtini, as the Sicilians call them. It is a traditional dish. What makes the dish particularly delicious and interesting is that they roll the rollatini in seasoned bread crumbs before grilling. The way I prepare the rollatini, they get a marvelous range of flavors by marinating before grilling in garlic, olive oil, and fresh thyme; then I smother them with a fresh tomato-and-lemon salsa after they’ve cooked (and try not to eat them for a couple of hours). The longer they sit—before and after grilling—the more flavorful they become. This is also a versatile preparation. Make as many rollatini as you want from a big piece of tuna, as I explain in the box, and schedule their marinating periods and quick grilling to your convenience. Serve them hot off the grill or later, at room temperature, when they taste even better. One rollatino makes a beautiful first course; two make a satisfying main course; a few rollatini slices make a terrific tuna sandwich for a picnic. And if you want to enjoy these any time of year—or if you don’t have a grill—just pop them in your oven (see below).
