There are everyday sandwiches and then there are heavenly combinations like this one the sweet, white flesh of tilapia crisply fried and sauced with olive-flecked tartar sauce. This is a sandwich for company, room temperature food of exactly the right kind-full of flavor, sophisticated, but easy to make. Accompany it with a bottle of good chilled white wine; then while away a summer afternoon.

For very practical reasons, we suggest you fry the fillets in advance. In that way, any smell of fish, which deters some people from cooking fish at home, should have disappeared from your house by the time you are ready to eat. To keep things really easy, make the tartar sauce ahead of time, too. This brings us to the bread: Pane Rustico, a variation of country bread, is crusty and not too flavorful. It is the contrast of textures-crustiness on the outside, and softness within that makes it so appealing. You will have to assemble the sandwiches before serving, but even so, when it comes to dishes that are good for entertaining, these tasty sandwiches figure near the top of the easy-to-prepare list.

Smoked mozzarella serves as the perfect counterpoint to the juiciness of roasted tomatoes here. Warming these sandwiches in the oven so that the cheese has barely melted makes this combination totally unforgettable. Good country bread is a must.

Smoked mozzarella is becoming more widely available, but if you can't find it, fresh mozzarella can be substituted. It won't be the same sandwich, but it will still be very good.

Even those who cannot go a day without meat will be happy with this satisfying sandwich. And while at first glance this may seem like a summer sandwich, it is wonderful year-round, especially in the fall or winter, when it makes the perfect complement to a bowl of hearty soup. The parts can be made beforehand: the peppers, well in advance, and the mushrooms, several hours ahead.
