I used to have trouble using the entire package of bacon. I would forget about it and soon end up with green, moldy bacon.
Then we bought this microwave bacon pan. You fold the strips over the supports and the grease drains off of each piece. You end up with crisp, bacon with less grease than cooking any other way.
I cook all of the bacon in the package, and when it is cool, I put it in a bag in the freezer. I can warm it in the microwave for a minute, if I want to have it with my eggs. If I need diced bacon pieces, I crush the frozen bacon and it breaks into little pieces.
