Foods to make for my dad who was just diagnosed, he’s 72.

2 weeks ago my dad was given a diagnoses of pancreatic cancer. The CT scans showed lesions in the liver. He also has been dealing with blood clots that started in the calf and spread to his lungs, brain, and now arms. He had 3 mini strokes 9 days ago. He doesn’t have an appetite for much foods at all right now so basically I am wondering if it’s okay that I make him the healthiest smash burger possible or a chili or something that we will actually want to eat.
