If you're going the sandwich route, whole-wheat bread nicely complements the strong flavors of tuna salad. If you're going the salad route, serve over leaves of lettuce like Bibb or Boston.

Broil until cheese melts and bubbles, 4-5 minutes. Remove tuna melts from broiler and serve immediately. A green salad or a mix of carrot, cucumber and celery sticks makes a nice accompaniment.
