1 cup chopped/coarsely ground walnuts
1/2 cup brown sugar
4 tsp butter
Mix the nuts and sugar well in a microwave safe bowl.
Place the butter in four pats on top of the nut mixture.
Microwave for a minute.
Mix well. Cool.
Sprinkle in oatmeal. Or yogurt.
Add cinnamon and nutmeg if you have the time for such frivolous niceties.
You could even melt the butter on the stovetop if you care more about cancer than you do having to wash another dish.
