Prepare the broth by heating it in a large pot over medium heat.
Add the minced garlic and ginger, sautéing until fragrant (about 1 minute).
Pour in the chicken or vegetable broth and soy sauce; stir to combine.
Bring the broth to a gentle simmer and add sliced mushrooms and chopped bok choy.
Carefully add the frozen potstickers to the simmering broth.
Simmer for about 5-7 minutes, or until potstickers are heated through.
Season with sesame oil, salt, and pepper according to your taste.
Serve in bowls, garnished with sliced green onions.
