<bot>: To prepare a healthy salad, start by selecting your base ingredients. Choose vegetables like leafy greens such as spinach and kale, or crunchy vegetables like bell peppers, cucumbers, and celery. Then add some lean proteins like chicken or turkey, nuts and seeds, or beans. Finally, top it off with some herbs and spices for flavor. For added nutrition, consider adding in a few tablespoons of low-fat dressing or vinaigrette.
