Wash celery stalks + remove any hard or browned ends.
Take one stalk and lie it face down on a cutting board. With a chef's knife, cut down along the stalk in roughly ¼-inch pieces.
Mince garlic and roughly chop parsley. Set aside.
Heat olive oil in a large pan over medium-high. When hot, add the minced garlic and cook for a couple minutes, stirring frequently.
Add chopped celery to the pan along with soy sauce/tamari, rice vinegar, and black pepper. Cook for approximately 8 minutes, stirring every 30-or-so seconds.
Turn off the heat and stir in the chopped parsley.
Taste and adjust seasonings as desired and serve hot.
