Most children like spaghetti (or love it!). When you make spaghetti, use spaghetti squash in place of the pasta. The squash is jam packed with beneficial nutrients, and it tastes great! You can use any tomato based sauce on it, including a thick meat sauce. I don't eat wheat or other grains (except oats, which I love), and the spaghetti squash is a fantastic alternative!
I would watch out when using sauces to cover up the taste of meats. They tend to be full of sugar and salt, both of which are terrible for children and adults alike. Have you tried serving a nice grilled or seared fish to your daughter? Salmon doesn't have that fishy taste, and there are few things that are better for us than wild caught salmon.
I have friends who are working on a web site that will be up soon. It deals with the ideal diet for the human body, and it addresses: weight, blood pressure, emotional well being, A.D.D., chronic pain, and all sorts of conditions. This plan (it's not diet alone!) helps to bring the body into balance. I can attest to its effectiveness.
In February, before I began this health plan, I was suffering from chronic pain caused by migraines, diagnosed fibromyalgia, TMJ, arthritis, and stress. My conditions still exist, but I have not had any of the old pain (not even one migraine, after many years of several full blown migraines per month) since beginning this plan. My traditional M.D.s have all told me they with they could get all their patients to eat the way I do, and they have been extremely impressed with my progress.
Try to feed your family foods that are fresh and free of additives. It's the healthiest way to eat. Use honey, maple syrup, or stevia as a sweetener in place of sugar. The aspartame type sweeteners are not good for us! Yummy fruits (those with lower glycemic index values) are a perfect choice for a sweet snack.
Have fun experimenting, and take care!
