Wheat thins and Cheez-its are considered crackers, not chips, so they are okay to serve any time. Grain based chips are chips that are comprised of grains, such as corn, wheat, rice, etc. Some examples include corn chips, tortilla chips, and Sunchips. The How-To Manual mentions cheese puffs, but we learned recently that USDA does not allow cheese puffs at all on CACFP, so this is not a creditable food item. Non-grain-based snack chips, such as potato chips, are not creditable in CACFP as well.
