Baby cereal can be mixed into just about anything. I've stirred some dry cereal into pasta sauce, mac and cheese, and applesauce. You can also use it to coat fruit or veggie chunks, just roll them in some dry cereal. If you can find wheat germ, that's another good source of iron that can be stirred into anything (I stir it into Tyler's yogurt). If you can find tofu, there are tons of ways to serve it to toddlers. Easiest is to cut it into chunks and offer it as finger food, or dry it off and fry it in some oil. You can also spread it on toast or sandwiches (works great in grilled cheese) or mash it up and mix it in other foods.
If you find that she gets constipated when you offer more grains, make sure you only offer whole grains. They're more nutritious and often aren't as constipating.
