I've been a vegetarian since the age of 5 (and I'm 37 & healthy, currently). I would suggest you get her eating Quinoa - it's the only COMPLETE protein grain, and can be found at Whole Foods or most healthfood stores. If you buy it, be sure to purchase the Ancient Harvest brand so it's already cleaned and ready to eat when you buy it. It can be eaten cooked like you'd cook rice (for every cup of quinoa, cook in 2 cups of water). You can cook quinoa with chopped green apples and cinnamon (or applesauce) for breakfast, for instance. You can also get her to eat a handful of natural (uncooked and unsalted) nuts to get a protein source, and/or peanut or almost butter. Beans and Rice = Whole protein, too, and there are other good protiens out there (yogurt, soy milk, etc.). Hope that helps!
