Penne with a sauce of tin tomatoes, garlic, a can of anchovies, an onion (removed at the end for texture) and some olives was maybe 50p a portion or something. Anchovies are the best thing basically.
The veggie has been away so I've been on a meat / fish binge lately, and I can confirm that this is the case.
i) pasta with broccoli, anchovies, garlic, chilli flakes, parmesan, olive oil for another tasty cheapish dinner
ii) Salad Niçoise - kind of customizable, I messed with the authenticity by using landcress instead of lettuce because it's going mad in the garden at the moment and putting potatoes in, which I think would get you lynched by proper french people, but yeah, tinned tuna, anchovies, black olives, tomato, sliced shallot, landcress, potatoes, hard boiled eggs, chives, vinaigrette. Buff.
Also, my new favourite steak sauce is chimichurri - basically a big bunch of flat leaf parsley minced with a few cloves of garlic, chilli, oregano, oil and vinegar.
