When Teddy had his Whipple and later radiation he pretty much didn’t like the taste of many things including his favorite, chocolate! I started out slowly by making old fashioned home style things (mostly chicken) like homemade chicken soup chock full of noodles, Chicken paprika over noodles, beef stew with the beef cut smaller than bite size. Nothing fried or too sweet. He loved cheese omlettes and deviled eggs. Spagetti sauce over small pasta. Everything in small potions, you can freeze the rest for later. Eventually his eating regime will return to normal but it takes time.
