I've been 'batching' it since BEFORE my divorce took effect several years ago. My micorwave died about 6 months or more ago and I haven't troubled to replace it. It's too convenient to use processed food if you have one.
I made a pineapple upsidedown cake for Easter in my cast iron skillet. (ya, it was based on a Duncan Hines mix)
I make tea by the pan full on the stove and when it's cold, I just keep drinking it till it's time for another pan full.
I know I still don't eat enough fresh fruit and vegetables. Who does?
