I quite often do pasta bakes at this time of year. My DP doesn’t eat fish, but if he did I would do tuna, otherwise we have:
Chorizo and broccoli, in a tomato sauce
Chicken and broccoli, in a creamy sauce
You could use frozen chicken, broccoli, onions, and garlic if need be. The chicken one is supposed to have ricotta cheese (I think it was a Jamie Oliver recipe originally) but I’ve done it with cheddar and parmesan if pushed.
Also with chorizo, I do a pasta thing with red peppers, an onion, tinned tomatoes, frozen peas, and chilli flakes. Or sub out the pasta for butter beans.
Chorizo is probably a good shout (if you like it, obviously!) because it keeps forever, and you don’t need much of it to get a strong flavour.
My DP makes a brilliant carbonara which is literally a couple of eggs, garlic, pancetta and parmesan, with spaghetti. I feel the same about pancetta as chorizo.
