We recently got a bit of paper out and wrote down ALL the meals we ever cook at home and then put initials next to it for who actually enjoys it.
ie
Steak dinner - A, N, J, S, D, C, S, P
bolog - S, D, A
fry up - J, A, C, S
roast - A, N, J, S, D, C, S, P
chilli - J, D
ect ect
Dead simple stuff obvs BUT
a) we thought of loads of meals we'd forgotten
and
b) turns out i'm cooking lots of meals on repeat that i don't like much thinking everyone else likes them and it turns out they don't! 

It resulted in a bit of a shake up and a renewed interest from everyone in what we're planning to have.
