If you haven't gotten the memo: Whole grains are healthy. Millet, barley, and oats are considered good carbs since they offer a great combination of fiber, protein, and vitamins; they fill you up and help you sustain your energy. One down side to whole grains is that they can take around 30 minutes to prepare. When foods take a while to cook, then we're less likely to eat them.
Make your life easier by boiling a few batches of whole grains on Sunday night. I like to make two cups of three different grains; usually rice, quinoa, and oats. Store them in tupperware containers in the fridge, so they're ready for you to warm up for any meal. You can enjoy them on their own or use them in your favorite recipes.
