Is there anything that says ‘comfort food’ like macaroni and cheese? The problem is, that on a low-carb diet, mac and cheese is usually a no-no. Not any more, though, because our new mac and cheese has only 150 calories, 16 grams of carbs per serving, but is chock full of 15 grams of protein. Trust us, you need this in your pantry asap. Seven servings per box.
