I had some fresh tortellini planned for lunch today. I didn't have any sauce, alas, so I wondered if I could perk them up a bit by grating cheese over them. Then it struck me that I could put the pasta with the cheese on it under the grill:

It was rather nice. You need a characterful cheese, ideally. I used some old cheddar. Don't skimp on the amount of cheese used.

I warn you that if you put a plate or bowl under the grill it will get mind-bendingly hot.
