Toss the popcorn with the olive oil, salt, and jalapeno seasoning mix in the paper bag. Fold the top of the bag over and staple the bag twice to close. Place the bag in the microwave and microwave on high for 2 minutes to 3 minutes, or until there are about 5 seconds between pops.
NOTE: Popcorn salt is a super-fine salt that is designed especially for sticking to food such as popcorn. It has the taste of regular table salt, but its granules are much finer.
