Put the chicken, water and sea salt in a crock pot. Cook for 10-12 hours on low setting. It's as simple as that. Add any additional ingredients that your child may be able to tolerate (i.e. rice, vegetables, etc).
My son (who has EE) loves this after his endoscopies. We take some with us to the hospital and he begs for it when he comes out of anesthesia.
I'm sure turkey could be substituted for the chicken.
