Very simple to make, and always a hit with kids. You can use other types of bread, I prefer French bread.
YUM! But seriously, 1 cup of mayo? I used 2 tablespoons. 4 stars because if I would have used 1 cup of mayo, I'm positive this would have been inedible. I omitted the onions, added a shake of garlic salt, and a little dill relish. I've never tried mozzarella on a tuna melt before, but it was awesome. Thank you! - 12 May 2008 (Review from Allrecipes USA and Canada)
Years ago my mom used to make chicken melts but she couldn't remember how she made them. As soon as I read this recipe, I knew this was it. She substituted canned chicken for the tuna, same amount of mayo (I used light), onion optional, cheddar cheese on a toasted english muffin. Bake it in the oven until warm and cheese is melted. Yum!! Thanks for helping me recreate my mom's recipe. - 13 Nov 2008 (Review from Allrecipes USA and Canada)
Too much mayonnaise and lacks flavor. Maybe use 1/2 cup of mayonnaise and add some garlic salt and black pepper. - 25 Jan 2004 (Review from Allrecipes USA and Canada)
