Make your own healthy snacks
Convenience costs money, so many snacks, even healthy ones, usually cost more when sold individually. Make your own snacks by purchasing large tubs of low-fat yogurt or cottage cheese and dividing them into one cup containers. For trail mix, combine nuts, dried fruit and whole grain pretzels or cereal; store small portions in airtight containers. Air-popped popcorn and whole fresh fruits in season also tend to cost less compared to prepackaged items.
Cook more, eat out less
Many foods prepared at home are cheaper and more nutritious. Also, convenience foods like frozen dinners, pre-cut vegetables and instant rice or oatmeal will cost you more than if you make them from scratch. Go back to basics and find a few simple and healthy recipes that your family enjoys.
