3 tbsp. butter
5 tbsp. grated Parmesan cheese
Onion salt (optional)
Pepper (optional)

Melt the butter over low heat and mix in the Parmesan cheese. Then use a big spoon to drizzle it over the popcorn. Sprinkle just a bit of onion salt and pepper on and then may be just a couple of shakes of Parmesan if you have any left.
