So glad to hear he is doing well.
He'll probably go back to loving the chicken shortly.
It sounds like the vet didn't mention that because high fat foods can trigger pancreatitis, there are many people foods that should never be given to pancreatitis patients including lunch meat.
Some meats are fine under the supervision of a vet (lean chicken, sometimes white meat turkey, etc.). If he won't eat the kibble, then he does need to have a balanced homecooked diet (if you want to go that way). A veterinary nutritionist can create a recipe for him. If it isn't balanced, it can lead to very serious health problems over time. Bloodwork is not a great indicator of whether or not a diet is working well.
We have dealt with pancreatitis here. My girl does eat homecooked food because she has so many medical issues. It has to be balanced though...
If you just put the kibble down that the vet wants your pup on, how long will he go without eating?
