Microwave bag of popcorn according to package directions, usually about 2 - 2 1/2 minutes.
Spread out popped popcorn to cool on a parchment or wax paper lined baking sheet.
Meanwhile, add 1/2 cup of melt chocolate chips to two bowls (1 cup total).
Melt white chocolate chips in the microwave. I heated for 1 minute at 70% power then stirred and heated again for 15 seconds until it was smooth and melted.
Add different shades food coloring to the melted chocolate and stir until you get your desired shade. I used neon green (3-4 drops) and traditional dark green (4 drops).
Using a spoon, drizzle both colors of white chocolate over popcorn.
Sprinkle on marshmallows and sixlets green candies.
Allow chocolate to harden then scoop into the jars.
Seal jars, add labels, and tie with a ribbon.
Present to your friends as a sweet (literally!) thank you!
Bonus! There's about a 1/2 cup or so left over for you to enjoy too!
