Here's a quick fix when you have no leftovers for lunch the next day.
When there are no leftovers, these tuna melts will definitely look like you’ve taken your time to prepare them. Not really. As I said, these are quick fixes. All you need are slices of bread, a can of tuna, a dab of mayonnaise, finely chopped celery, finely chopped green onions, dash of salt and pepper. Mix all the ingredients together except for the bread. Spread over slice of bread. Top with grated cheese. Put in oven toaster and bake until cheese melts. Tadaa!! Delicious
