Stir-fries are a great way to incorporate a variety of vegetables into your child's diet. Heat some olive oil in a pan and add diced chicken breast. Cook until the chicken is no longer pink, then add a mix of colorful vegetables like broccoli, carrots, and snap peas. Stir-fry until the vegetables are tender-crisp. Season with soy sauce and serve over steamed rice or noodles. This dish is not only delicious but also packed with vitamins and minerals.
