This is totally my type of cooking 
We do these:
Pasta or spaghetti:
With pesto
Plain with grated cheese
With jar tomato sauce, sweetcorn and cut up cooked sausage
With jar tomato sauce and frozen vegan "meatballs" (cooked in oven)
With leftover or slow cooker bolognese sauce
Microwave jacket potato (small/medium potato) with butter and:
Grated cheese
Baked beans
Tuna mayo
Corned beef
Cut up ham
Instant noodles drained of the salty stock or plain egg noodles with a splash of soy sauce, with grated carrot, sweetcorn, chopped ham.
Air fryer fish fingers/chicken nuggets and chips, waffles or smileys
Maybe with frozen veg too (I love the Bird's Eye microwave ones)
Ravioli from a tin, microwaved. If still young the Hipp baby ones are very good.
Ready made lasagne, also graduated from Hipp baby one.
Rice from rice cooker with slow-cooker/leftover curry, chilli etc, or just with veg stirred in.
Stir fry with pre-cut veg and pre-made sauce bought from supermarket.
