What can I make with melted cheddar?

I was going to make cheese and broccoli crepes for a friends' children, but I didn't read the recipe before I started cooking. I made the batter, but I'm supposed to refrigerate it for an hour, but I already got the double boiler on and the cheese is already melted. So, what I can make that's quick with melted cheddar? I can remelt more after my crepe batter is ready.
