Food mainly, although I did once whip up a rather delicious hadron collider once. (JOKE!)
On topic:
Quite a bit actually. Most of it's a variation on pasta with something or rice with something but sometimes that's enough. I can do soups, stews, scrambled eggs and gravy as well, so as far as varity I'm not going to get board and resort to take-aways all that much. (Even if I will be Mrs-7-recipes).
I'm living in a house not halls next year for Uni so I'm looking forward to cooking for myself.
Considering I know people who can't even boil an egg, anyone who can cook pasta properly is ahead of the curve in my books!
