Microwave Popcorn (without the oil, salt and expense of storebought bags)

This post from100 days of real food sums up my thoughts (exactly) making your own microwave popcorn. Bottom line, it works, well.
I just went to the store and paid $1 for 50 brown paper lunch sacks and another 1.88 for a 32 oz bag of popcorn. I used 1/3 rd cup popcorn and ended up with 12 bags (that's .24 a bag) and fatsecret says that 1/3 cup of un-popped corn will be 172 calories. 
So make yourself up a bag... or a dozen and have it on-hand on the cheap for your diet fix.
YOUR WELCOME!
