Place the eggs in a small saucepan and cover with water; bring to a boil, then cover, remove from heat, and let sit for 9 minutes.
Transfer the eggs to an ice bath to cool, then peel and slice them in half.
In a small mixing bowl, combine the almond butter and collagen peptides, stirring vigorously until the powder is fully incorporated and the mixture is smooth.
Wash the celery stalks thoroughly and pat them completely dry with a paper towel.
Trim the ends of the celery and cut each stalk into 3 or 4-inch long pieces.
Using a small spatula or spoon, fill the hollow center of each celery piece with the almond butter mixture.
Sprinkle the hemp hearts evenly over the almond butter filling, pressing down slightly so they adhere.
Arrange the filled celery sticks on a plate alongside the halved eggs.
Season the eggs with sea salt and black pepper before serving.
