Food Poisoning - 15 month old not eating

My baby got food poisoning and is not eating. I don’t know what to give her. Please help. She has been drinking pedialyte, apple juice, and chamomile tea. Sometimes she eats a little bit of pasta or bread. But I can’t get her to eat much at all. Then she cries because I think she is hungry. And she won’t let me feed her. She has to be the one feeding herself. She won’t open her mouth if I try to feed her anything with a spoon, like soups or baby cereal. It has to be her grabbing the food.
