This was the first thing I learned to cook. In fact for a while it was the only thing I knew how to cook. I used to make all sorts of variations on it. Whenever we had leftover roast meat of any kind this is what I would do with it, and if I didn’t have any leftovers, I’d use minced beef. And when I had a vegetarian girlfriend — which seemed to happen a lot — I’d do it with vege mince.
It’s real comfort food. If you are a student you could probably live on it.
Color is key here, it should be bright and colorful not a sludgy brown. Go easy on the liquid, but don’t let it dry out and burn. The vegetables should end up still crisp, not mushy and the spice should not blow your socks off.
