This decadent comfort food gets a muscle-building protein kick with whey. You can find unflavored whey protein on Amazon. To add more protein, use Barilla Protein-plus elbow pasta. With protein pasta, expect about 25g of protein and 300 calories for a serving (half of this recipe). Add in veggies if you need more food to fill you up but still keep the calories low.
