I have the Baby Bullet, but any food processor should work. . . Put 1/2 cup of oatmeal, brown rice, or other grain in the food processor and make it into a fine powder. On the stovetop, add the powder to 4 cups of water and boil for 20 minutes (stirring often and watch it so it doesn't boil over - trust me on this one). I freeze it in cubes and mix the cubes with fruits and / or veggies.
