I'm the oldest of 3 kids, and when I was in high school my mom started a new "tradition": Each person in the family was assigned one night a week that they were in charge of dinner. If it was your night, you planned the menu, checked ingredients, added stuff to the weekly grocery list, and either did the cooking or "supervised" the cooking. If you cooked or helped to cook, you didn't have to help clean up. So 5 nights of the week we had "home cooked" meals, one night we were all crazy with lessons, etc. so everyone was on their own for dinner, and every Friday was "the week in review" - aka leftovers! We'd spread out all the leftovers on the counter, and each person would make their own plate of what they wanted and nuke it or eat it cold as desired.
To this day, I always feel like I should be saving my leftovers for "The Week in Review", but DH just takes it all to work for his lunches.
