he says he knows how to eat an MRE. 
It was really just debates on whether to microwave, boil, or grill them... we went with grill. 

Really, he fed himself for years when he was in the dorms and living with his room mates. When we started dating, I took over cooking. He focused instead on his games, so he doesn't need to think about food. 
Honestly, I've even been that wife who held the pizza to his lips once in a while so he could eat and play at the same time.
