My son loves popcorn in his morning tea snack. He usually requests this as I am hurrying to finish lunches, about 15min before we are meant to be out the door.
One of the mums at our preschool showed me how to make popcorn using a paper bag in the microwave. I can easily make one serving while finishing up the other lunches.
You can spray it with some flavoured oil or sprinkle with salt but we tend to love the flavour of just the warm popcorn!
Ingredients
1 lunch paper bag
1/4 cup popcorn kernels
Directions
Put the popcorn in the paper bag and make two small to close the bag (otherwise there is popcorn everywhere!).
Cook in the microwave for about 2 minutes. You’ll have to listen to see when the popping starts to slow down or else you will burn your popcorn and the kids won’t be impressed. Your microwave might vary on the cooking time.
As I do prefer popcorn cooked on the stove, this is a brilliant time-saver in the morning and easy cleanup!

This is so smart. Lunch sacks and some raw popcorn kernels sure would be a lot less expensive than those microwave bags of popcorn.
Much cheaper and since my son is the only one allowed to take it to school, I can just make a little bit just for him.
