Maren Stein, MS, RD, a clinical dietitian at Adventist Health Simi Valley, said her favourite packable lunch is a taco salad: mixed greens, spicy chicken or tofu, corn and black bean salsa, bell peppers, avocado, and tortilla chips with a creamy ranch dressing. "This provides a good balance of vegetables, carbohydrates, protein, and healthy fats that is a filling, delicious, and easy lunch," she told POPSUGAR.
