Here's an Italian take on the classic grilled cheese.
Slice bread to desired thickness. Spread one side of each slice with either butter or olive oil (your choice). Place butter/oil side down in a non-stick skillet.Grate the cheese and distribute on the bread. Add the anchovies and the pesto.Turn on skillet to a medium heat. Let the bread get nice and brown on the bottom. As this happens, the cheese should melt a bit.Take the two sides out and put them together.
