I am a tuna fish lover but am forever looking for different ways to use it. One of the restaurants downtown used to serve a tuna melt sandwich and it was so good. My version of their sandwich is very similar...It was served with a dill pickle and kettle fries...This picture is from tunasalad.com. I will post one of my own soon.
Mix all ingredients together down to the salt and pepper....
Spread softened butter spread on one side of bread.
Doing only a couple at a time, put two sliced of the bread into a hot skillet, butter side down. Add a piece of the velvetta cheese on the bread followed by a heaping tbs. of tuna. Mash it down flat with you spoon and top with another slice of cheese. Top with final piece of breat, butter side up...When the bread starts smoking just a little bit, carefully flip over with a pancake turner to brown the other side. Remove from skillet when both sides are a golden brown.
