When my husband was going thru his chemo, our dietician said he could eat whatever he liked & advised me to 'value add' as well - like full cream milk, normal cheese (not lite) etc
When he was at his worst - he suddenly took a liking to KFC Chicken Wraps & their lovely Berry Smoothie (not sure if they do the smoothie now!) SO ..... every lunch time - off we'd to go KFC! He also took a liking to our local bakery (Steak & Kidney Pies) so I'd buy up 6 at a time for him!
Just Eat whatever you THINK you might fancy - even if you DON'T fancy it! and maybe even try something new with exotic flavours (like Thai Food perhaps - which is really colourful and not as spicy as Chinese?)
All the best xx
