When I go grocery shopping instead of buying the pre-packaged snack stuff for lunch I will buy say a bag/box of cookies and when I get home I put a set number of cookies into snack bags. It also helps to cut down on the partial box/bags of things open...this works for larger bags of chips, gold fish crackers and such. I then have two larger totes one for healthy snacks and one for cookies and such. I put all of those pre-made snack bags into the larger totes and then tell the kids to pick two snacks from each of the totes for their lunch. Makes mornings go smoother.
