My super picky child liked the plain beef ones. She was allergic to eggs, dairy, soy and shellfish and we avoided nuts and seeds, I remember how hard it was. She did outgrow all by K age. Highly recommend Dr. Wood at Hopkins if you need someone excellent for food allergies. POFAK the online group was a life saver as well. Fingers crossed that it goes well! Hot dogs travel well in some boiled water in a thermos, I hope you can add them.
