This meatloaf is healthy because it substitutes ground chicken for the traditional ground beef. Chicken is a leaner protein, so it contributes less added fat to the meal. The use of ground chicken keeps the overall taste and integrity of a classic meatloaf, keeping it light and flavorful without the greasy, heavy beef. As well, the addition of fresh carrots, celery, garlic, and onions allows you to add a variety of vitamins and nutrients, improving the flavor and texture as well.
