A friend of mine’s go-to meal when she’s exhausted or just can’t be bothered is Shit On Toast, which can be any kind of other foodstuff (beans, tinned ravioli, spaghetti hoops etc.) placed on top of toast.
Another friend swears by Eggs Is Eggs, which comprises... eggs.
In our house, similar meals in the rotation include:
Stuff On A Tray (which involves placing the contents of the fridge on a tray and putting it in the middle of the table with a fistful of cutlery)
Vegan Slop (self-explanatory)
Noodles In A Bowl (fancy)
...any of which could be garnished with a clump of cress, a crescent of crisps, and/or a hot egg.
What are your similar rubbish but well-beloved standbys?
