For a refreshing and nutritious veggie sandwich, try an avocado and sprouts sandwich. Start with a whole grain bread and spread some mashed avocado on one side. Layer on fresh sprouts, such as alfalfa or broccoli sprouts, for a crunchy texture. Add some sliced tomatoes, cucumbers, and red onions for extra flavor and color. Drizzle with a squeeze of lemon juice and sprinkle with salt and pepper. This sandwich is packed with healthy fats from the avocado and vitamins from the sprouts, making it a great choice for a light and healthy meal.
