My first round of radiation it took me 7 weeks to even attempt eating foods like cream of wheat, then adding peaches, scrambled eggs, and they were by teaspoons the most, and relied on canned nutrition. My first true meal was 7 months later on Thanksgiving, which was no feast, so it takes time. I just kept trying foods I knew the taste from memory, sometimes only eating a bite or two, but kept it up until I could taste something. When ordering Chinese takeout I would order like 7 dishes to see what I liked. Probably watching the cooking channel helped my desire. This day, I can eat everything, taste most everything, minus recent tooth problems.
Tasting is just more than eating. It involves memory, seeing, hearing, smelling, textures, tasting, and the 5 taste senses, really there are more...salt, sour, bitter, sweet, umami, and I like fattiness, as the 6th. I incorporate all these, at least try, in cooking, and eating. Even the room ambience, colors effect eating habits. During, immediately after treatment, it didn't work as well as in later months.
As far as recipes, I have so many. Since I started eating after radiation, three years ago, I took photos of most dishes I made, ate out, so it was kind of fun to do, eat, even if it was very little. I may have 1,000 photos or so.
Good luck.
