Plan and Prep Your Meals
I can't stress enough how important this is. This part is time consuming and there's no way around it, but if you don't do it you're almost guaranteed to spend more money. I planned meals that I could make on Sunday and use throughout most of the week. For example, I'd buy a whole turkey and get at least four days' worth of meals. Think turkey pot pie, turkey soup, turkey chili, turkey salad, or, if you're fancy (I'm not), something like turkey tetrazzini. By the end of the week, we were sick to death of turkey, but hey, It was part of the challenge. Get creative!
