I've been playing around with sprinkling almond meal on top of my kids' breakfast cereal in order to give them a protein boost, and (to my surprise) they love it. Never one to leave well enough alone, I hit on the idea that nutty cinnamon toast would be delicious. I cut the traditional sugar/spice mixture with almond meal and lo! higher-protein cinnamon toast! Even better when you use a good-quality whole grain bread.
Measurements are to taste; everyone's cinnamon-to-sugar preference is different. If you're looking to avoid refined sugar, a natural sweetener such as date sugar or coconut sugar works wonderfully. Bonus: you can stir this mixture into oatmeal or yogurt with yummy results as well.
You can buy almond meal, but there's really no need — just powder a handful or two of raw, unsalted almonds in your food processor or blender. Then sprinkle with abandon!
