Add 2 Tablespoons of popcorn kernels to a sandwich Stasher bag (or larger). Seal bag, leaving about 1 inch open to release steam. You can also use a brown paper bag. Roll it up and place in microwave, rolled side down.
Microwave for 2-3 minutes, or until popcorn stops popping for 15-ish seconds.
Remove from microwave, and seal. Set aside.
Add 2 Tablespoons of chocolate chips and ¼ teaspoon oil to a small microwave safe bowl. Microwave for 30 seconds at a time, stir between, until melted.
While chocolate is in microwave, lightly spray popcorn with cooking spray, and add ½ teaspoon salt. Shake bag vigorously. Taste. Add more spray/salt if desired. Barely under-salt your popcorn as you will add more salt to finish it.
Once chocolate is melted and smooth, shake about ⅓ of the popcorn into a serving bowl. Then drizzle about ⅓ of chocolate over it. Repeat until all popcorn and chocolate is used.
Add additional salt, if desired.
You can refrigerate popcorn to cool the chocolate, or enjoy it immediately. Either works.
