This is an incredibly easy sandwich to make. I never thought of it before today when I was making my son some fish sticks, and he said he wanted it on a sandwich. Voila!
Cook 4 fish sticks according to the package directions.
Butter two slices of bread (like you would a grilled cheese).
Put the butter side down on a heated skillet.
Top each slice of bread with a slice of cheese.
When the bread starts to brown, put the fish sticks on top of one of the slices, and put the other slice on top of that, cheese side down (like a grilled cheese).
When the sandwich is browned to your liking, remove from skillet, let cool, then slice in half.
