Alright, in that case I'm sticking with my suggestion of spaghetti, olive oil and garlic and awarding myself bonus points for only using one ingredient
I like the omelette idea. Ham omelette with chips! Only I'm crap at making omelettes so I will let café rouge cook it for me (they're the only outfit round here that doesn't incinerate omelettes).
You could make a decent curry under these updated rules:
Chopped tomatoes
Onion
Meat
(Cumin seed, coriander seed, garam masala, garlic, chilli, salt and pepper all free)
The drawback is that you won't have any rice or bread to go with it, but I could live with that.
Some other thoughts:
Bruschetta (bread and tomatoes, with oil, vinegar, garlic and herbs all free)
Fajitas (tortillas, meat and onion, with spices free)
Chicken noodle soup (chicken, stock and pasta, with herbs free. And garlic and chilli too, because I put those in everything that can accommodate them and most things that can't)
You could also do one of my previous offerings properly now, and make a bastardised version of an amatriciana: bacon (or lardons or pancetta), finely sliced onion, spaghetti (with free garlic, chilli and herbs). I think I've mentioned before on here that this is my all-time winner in the "best flavour for least hassle" contest, but be careful about calling it an amatriciana because the people of Amatrice
will issue a fatwa against you.
Edit: shit, that won't work; I forgot the tomatoes. OK, replace the onion with passata or chopped tomatoes, but try to sneak in some sliced onion when Cassini isn't looking.
