I just try to make sure we have something from each of those four food groups every day. Fruits, grains, veggies and nuts. I keep jars of nuts on the counter for everyone to dip into whenever they want a snack. Walnuts, cashews, pecans, pistachios, pepitas (pumpkin seeds). Toasted, either not salted or lightly salted. Good source of protein, much better than bags of chips which are just salt, sugar and empty calories, a waste of money.
