Now you have me craving sweet and sour chicken! My mother used to make a killer sweet and sour when I was a kid, totally from scratch. Since it's just for me, I can't be bothered. My version goes, chop up chicken fillet, add some onion/mushroom/pepper, stirfry, open jar of Uncle Ben's (yeah, has tomatoes), open packet of instant noodles/rice, nuke, serve.

Oh and since DH doesn't eat tomatoes either, we just brown the mince, add a stock cube and herbs, simmer until cooked and then thicken with cornflour. Goes nicely with mashed potatoes, even if you don't make a cottage pie out of it.
