Have her eat raw tomatoes on an empty stomach. If no reaction, then you ruled it out.

I am pp who thinks tomatoes. I have always had issue with peppers too. Vomiting and migraines. Never do I touch any peppers.

OP, note that tomatoes are on the list in the link I posted. of course, most pizzas have cooked tomatoes. If you have raw(ish) tomAto as a topping, then they could be a more likely potential cause.

Thanks, but I don’t think it’s the tomatoes. We have caprese salad for dinner almost every night during the summer. DD loves it.

Does she have the same reaction if she has other foods with a high amount of Red 40?

I have a kid allergic to Red 40 and that's the reaction she has if she ingests too much. Believe it or not, pasta/pizza sauce and pepperoni both have Red 40.

Since you mentioned she drinks milk without issue, and eats cheese without issue, and has tomatoes without issue.

Tomatoes. I would be almost 100% sure it is tomatoes. It is in some weird oral and pollen allergy. What other veggies and fruits bother her? I have the same, it is awful and can be combined with GERD.
