It's good to hear that you bit and bought some steak. I certainly am not suggesting that you eat foods you don't like, or that you should eat red meat all the time, but once in a while it would surely do more good than harm.
I find it interesting that one of the reasons you don't eat beef is that it doesn't prepare well in the microwave. Quite frankly, no meat, fish, or poultry prepares particularly well in the microwave. I think you should invest in a grill of some sort.
