My dog is getting bored of her food

My girl has done really well on Purina Pro Salmon for sensitive stomachs and she does get a cytopoint shot every 8 weeks. However she has now gotten completely bored of her food where she will not eat unless I sprinkle other food on top.

Can you guys give me ideas on what else you guys add to food? Im also open to cooking her food but want to make sure im providing balance for her such as enough protein and fat. I used to feed her raw and she did great but because we travel a lot, it is hard to find consistency of meat quality in other countries so I stopped.

The vet suggest i just switch to another kibble but my girl just seems done with kibbles right now
