have you thought about veggie dogs, they're probably a bit more nutricious and there usually isn't a "skin" on them like on regular hot dogs, so there is less of a risk of choking.
I like to cut tofu in slices and use shake and bake on it. It only cooks for about 10 minutes.
You can also marinate tofu in salad dressing and just have it plain.
Macaroni and cottage cheese mixed together has always been a favorite of mine and my sons (I know it sounds gross but try it)
What about a baked potato loaded with cheese and veggies since she liked potatoes with sour cream. Also maybe a potato based soup like cream of cauliflour or cream of broccoli. If you make it yourself you can also make it thick enough that MAYBE she can feed it to herself without getting too messy. Although it's probably not the right season for soup-way too hot
finally, Jam sandwiches- my son often just likes cut up, mushed up berries instead of jam.
Good luck , Lorrie
