Disney is so great with food allergies. My DM has to seriously watch her salt and my DH can’t have dairy or black pepper and also has to watch his salt. In DS we ate at the Edison. They had a burger and fries. I can’t remember if it was there but the TS places at Disney in the parks and resorts where we eat when we visit every few years have pieces of meat whether beef or chicken they set aside and do not marinate which they cook in no salt no dairy cooking spray and she would have fries or potatoes and steamed veggies. Sometimes a salad as an appetizer with oil and vinegar dressing. At Tutto Italia in Epcot they cooked pasta in no salt water. We can eat at buffets where they walk you around and also have food made in the back. For breakfast last trip we stayed at POR and in the food court a chef made fresh eggs for them in the back. If we were at TS they usually had eggs made with no salt cooking spray, potatoes, and fruit. But, certain fruits are high in sodium or interact with medicines so she could only have certain kinds.
