How many different meals a week are in rotation for your family?

Hey all, I’ve recently moved in with my partner and his teenager and have gone from cooking for one, to cooking for three.

Can I ask, do most families have something different every night or is there some crossover with leftovers? Also, do most people have a few meals in rotation that they might make weekly or is every week new meals also?

The pair are used to getting alot of takeaway so I feel a lot of pressure to maintain the novelty of new meals -however I’m used to eating very simply - protein, salad, veg etc, but they like a bit more variety!

Would love some input and advice!
