Why do you meal prep?

I meal prep a week's worth of food every week, mostly because I'm tired when I get home from work and don't want to spend time cooking a meal every day after a long commute. Now, I usually cook for a whole day on the weekends and a have a week's worth of food ready in less than 2 hours.<br><br>What reasons do you have for meal prepping? Do you meal prep for health reasons, to save time, money, etc.?
