No new food

I have a very picky eater, my son is 2.5 yrs old and I made this list for his food therapist. He's been in food therapy for a few months now and nothing has changed. He doesn't have a problem with textures, colors or anything he simply won't try the food at all. The stuff on this list are the only things he eats and it's so frustrating. I feel like every day is the same routine with the same foods and sometimes he won't even eat these foods! I can tell he's tired of the same foods but refuses to try anything else I make him. Idk what else to do 😪
