The Chicken Marsala, Tuscan-Grilled Chicken, and Prosciutto-wrapped Pork Tenderloin — all found on the Carrabba's Under 600 Calories menu — are delightfully low in carbs. For an appetizer, try the Mussels in White Wine Lemon Butter, Tomato Caprese With Fresh Burrata (hold the balsamic glaze), or Grilled Asparagus With Prosciutto (same here).
