Not a freezer meal, but I keep seeing "overnight oatmeal" on healthy eating blogs. Mix 1/3 cup raw rolled oats with equal parts milk and yogurt(or liquid of choice, I think 1 cup combined), and add any other flavors or toppings in the morning. You can google this. Use a jar, like a mason jar, and pretty much add whatever you like to it. Some use honey, seeds, toasted coconut, fresh or frozen fruits(frozen blueberries would be added the night before so they thaw).
I thought of this thread because a college student gave it a great review, for being easy, yummy, and quick.
