This Low Calorie Cream Gravy Recipe is just 138 calories and can be made in 15 minutes or less!I added a small amount of heavy cream at the very last moment top give it that flavor. You can choose to skip it as buying heavy cream for just 1 tablespoon seams a bit silly. Special Tip: You can use whatever milk you like, almond milk will have the lowest calories and also naturally boosts metabolism.
