On the stove, boil water and add in your oats. Take half your peach, remove the skin, and cut it up. Place the cut peach into the pot with the oats and stir, trying to mash some of the peach. Add in your sweetener (like a Splenda packet). Once all the water is cooked out, stir in protein powder (optional). After, stir in some yogurt (Greek yogurt is recommended for its thickness). Top with more peaches, additional yogurt, and whatever else you desire!
