While there was nothing really wrong with these sandwiches, there are better recipes. For example, we enjoy melted Mozzarella cheese on many things, but not on these. It was just too bland (I wound up sprinkling all of the sandwiches with grated parmesan just to get some flavor). In the future, I will continue to use either Swiss, American or Provolone when I make Tuna melts for my family. And while we like Hamburger buns when I make hamburgers, we prefer I use more "flavorful" breads for tuna melts (some variations might include English muffins, seeded sandwich rye or potato bread). My daughter doesn't like tomatoes (she's 22 years old, so I think it's time she gets over that) so instead of slicing up a "beefsteak" or 2, I usually just halve or quarter some cherry or grape tomatoes and include them in the salad. Also, since we all like lettuce but some of us find it too "cumbersome" to top a sandwich with, I often simply run some through the food processor and fold it, too, right into the salad (a good "trick" to use if you've got older young children -- ages 7-10 or 11, perhaps; most of the time, they won't even know it's there, so they won't complain and even kids who actually like lettuce will find it easier to eat this way.) Oh, yes -- we're 6 adults (and my daughter is pregnant), so I use no fewer than 3 and sometimes 4 cans of Tuna; I can't imagine getting 4 servings from 1 6 oz. can.
