Either pop the unpopped popcorn or pour the pre-popped popcorn into a big bowl, put to the side.
Heat the vegan butter in a sauce pan over low to medium heat for a minute or until it melts. Add the hemp seeds and sea salt and mix well.
Pour the butter-hemp seed mixture over the popcorn and toss with large spoons or spatulas.
Keep some napkins on hand as it can be a bit greasy. Enjoy!
