Cook macaroni, about 8-10 mins. Drain. While macaroni is sitting in colander, mix soy milk, and nutritional yeast in the pan. Return macaroni to pan and mix. Salt and pepper to taste and then add the two slices of cheese. Turn burner on if needed to melt cheese. Continue to stir until cheese is melted.
I had a big craving for mac and cheese tonight and so I just through a few things together and they seemed to work out for me. I liked it and thought it tasted a lot like stuff I used to make with Velveta back in my dairy-eating days.
