Fresh choices, steamed or grilled, and lightly seasoned can be delicious. If it's been years since you've tasted a vegetable you liked, give it one more shot-you may find that your taste have changed. Practice what you preach. Set a good example for your kids. Your chances of getting them to eat broccoli are almost nil if you won't try it.
Herbs are nutritious, too.
Add a cup of chopped fresh herbs to a salad for your family-you'll add nutrients and cut down on the salad dressing you use. If at first you don't succeed, keep at it. A child who won't try tomato today, tomorrow or next week might give it a shot next month. Easy on cheese. Cheese is nutritious but can be high in fat.
