Believe it or not, I'm allergic to raw fruits and vegatables lol.
It's an enzyme that breaks down when heated, according to my allergist...
Lots of steamed veggies with butter for this guy
To answer your question, I find that I just keep eating the stuff I really like (beef, chicken, pork, eggs, broccoli, sugar snap peas, yams, spinach, bacon) and I don't really get bored. I do eat dairy and sometimes utilize protein shakes, unlike some others though.
