Canned and pouch tuna are great pantry staples to regularly keep on hand. While you might think of tuna salad as being cold, warming it up for a satisfying melt is a wonderful spin that only takes one extra step. Golden crispy bread paired with the savory tuna and boldness of Cheddar makes the perfect bite for this handheld entrée that comes together in less than 15 minutes. — Robin Fields, The Easy Three-Ingredient College Cookbook
