Wash lettuce, remove core and arrange the leaves on a platter in a circular pattern.
In a glass jar with tight-fitting lid, add the olive oil, vinegar and a pinch of salt. Seal the jar and shake vigorously to emulsify the ingredients. Set aside.
In a small skillet, add butter, garlic, hemp hearts and a pinch of salt. Cook the contents over medium heat, stirring constantly. The hemp hearts will toast quickly, so keep an eye on the pan the entire time. When hemp hearts are golden brown and the garlic is fragrant, remove the pan from the heat and immediately pour the hemp hearts out onto a plate to cool.
To assemble the salad, give the dressing one last shake and drizzle it over the butter lettuce. Top the salad with the toasted hemp hearts and enjoy!
