If I don't have a menu for the week - I won't stay on track.
As long as I have a plan, we are good! I try to make my menu for a week or so at a time so I can make sure I can get what we need and thaw things out in time. It also helps me budget, because I buy what I need for the menu.
Sometimes things get mixed around or we end up needing more or less - but I at least know what I have on hand to make.
I realized that leftover nights are wonderful! Cook once and eat twice - YES! Sides for dinner are usually some kind of veggie that I can fix up quickly.
