1. Plan Your Meals. This can be as basic as choosing the main component of each meal you intend on preparing or as specific as picking out recipes. Keep it simple and choose two or three breakfast and lunch options you can use throughout the week. Save money at the grocery store by taking an inventory of your pantry and fridge and planning meals around items you have on hand like beans, grains and excess produce. If you store fruits, vegetables and animal proteins in the freezer, plan to use a few of those items, as frozen foods do not have an unlimited shelf life.
