Honestly, even the meat options in the hospital are nutritionally lacking. Hospital food, in general, is utterly bad, IMO. I eat vegan, my partner eats meat, and when he was in the hospital, the food was just awful. It certainly wasn't helping him to get better.
I brought him meals every single day, as a result.
Do you have anyone who could bring meals to you? Even a good meal, twice a week, is bound to help. And some things you can keep in a cooler or mini fridge even (if they allow that) and just reach over and prepare it yourself (without getting out of bed).
Apples and oranges keep really well - a big basket of those could help for snacks. Green peppers also keep well.
