Packing a healthy lunch for work or school is the easiest way to keep your diet on track. The key is creating a balanced lunch that has a lot of lean protein, whole grains and fresh veggies. Sandwiches are a lunchtime classic--try stacking leftover steak or chicken on multi-grain bread with pickled tomatoes, garlicky pesto or tahini sauce for a flavorful and delicious upgrade. Toss leafy greens with seasonal vegetables, roasted nuts, grilled shrimp and tangy vinaigrette for a tasty lunchtime salad.
