“Our vet said there were rx hypoallergenic foods, but at the time that we had her tested (a year ago), he recommended that we remain on the i/d since we had finally sorted out her (severe) stomach issues”.
I would continue to work with your vet and get his approval regarding changes.

My dog with a sensitive stomach and allergies does well on Nutrisca salmon and chickpea http://www.chewy.com/dog/dogswell-nutrisca-grain-free-salmon/dp/35031
Eating grass sometimes indicates that the dog has an upset stomach….proceed with caution.
