Greek yogurt is one of the better high-protein snacks you can keep on hand, but buying it prepackaged adds up quickly. Making your own and portioning it into snack cups brings the cost down to about 50 cents each. That works out to close to $300 a year in savings for me, which is a meaningful number for something I eat almost every day.

The cups themselves take about 15 minutes to prep if you are making a batch of 8 at once, which is what I usually do. They sit in the fridge all week and are ready to grab whenever you need something quick and filling. If you are not making your own yogurt yet, I walk through my process at the end of this post. It is simpler than it sounds.

This is the breakfast I actually eat every morning. Not the one I intend to make when I am feeling ambitious on a Sunday, but the one that is actually in the fridge waiting for me. Overnight oats with whey protein, Greek yogurt, flax seed, mixed nuts, and frozen berries. It delivers 37 grams of protein and keeps me full significantly longer than anything that comes in a pouch.

The upfront cost is higher than it looks because some ingredients like protein powder and nuts come in larger packages, but once you have those the per-serving cost comes out to about $2.21. A 42 oz container of oats and a bag of flax seed will cover nearly 4 batches. A bag of nuts covers 3. The protein powder alone will last over 5 batches. The only things you re-buy regularly are milk, frozen berries, and Greek yogurt.

There is also a reason beyond convenience for why this particular breakfast is worth being specific about, and it has nothing to do with the taste.
