Eggs and rice plus fridge/freezer stuff for egg fried rice.
Instant noodles - Asian import ones are the best - for cup a soup type noodle (add random fridge stuff which will "cook" in the boiling water) or proper stir fry.
Pasta, pasta sauce plus whatever is in fridge
"Lunch dinner" - ham, salami, cucumber, peppers, tomatoes, crackers/breadsticks/crisps etc
Jacket potato with tuna or beans - OK potato not quick but low maintenance.
Tuna pasta salad
Frozen chips and fish fingers/chicken nuggets/schnitzel/etc. With froz peas or baked beans if I can be arsed.
Frozen pizza, ready meals (Aldi do a nice steam one)
Ham, egg, chips and beans - yum.
Stuff on toast
Mushrooms plus packet curry mix which is like curry sauce - quick and dirty but goes amazing with chips, or could have with rice. I do it with chicken if we have any but more often mushrooms + onion and frozen peas to add green.
Jar sweet and sour sauce for chicken with rice. When I lived in the UK we used to have chicken tonight type sauces quite often too with chicken and rice or mash.
I don't really bother with complicated or longwinded meals very often!
