Here is an example of something he has made. Let me tell you it does not sound very appetizing to me, but he says it is not that bad.
You cook the ramen noodles in the microwave. DO NOT USE PACKET for this recipe. When done cooking the noodles, add a package of tuna. Then you add some mayo and relish and mix it around. You now have a Tuna casserole. Not very complex but he said it tastes pretty good. Well as good as it can at least.
He did say that ramen noodles are the way to go for now, but when he gets out he will never eat another package! Poor guy. I wish I could cook him a nice meal.
