As I don't have a Pantry of Plenty we tend to rotate meals in our house. But it's not like we have Fajita Fridays every week (sadly) or anything like that, but we tend to have a staple of 6 or 7 dishes that get tweaked or form a base for a meal. I think that's perfectly normal and acceptable.
Normally we limit it to one pasta dish a week, one red meat dish a week and then the rest if a variety of chicken/fish/veggie.
Broccoli with everything though
edit: also disclaimer - almost always make things from scratch, we hardly ever use jars.
