I also work full days so what I often do is cook supper the night before. For example, I’ll prepare Monday’s supper on Sunday. Monday evening, after we’ve eaten, done homework, etc., I’ll put up Tuesday’s supper. Reheating is quick and I’m not limited to things that don’t take long to cook.
I’m a huge proponent of cook once, eat twice. You can either freeze half of what you’ve made or just serve it a couple of days later – depends how picky your family is about planned-overs, aka leftovers.
