Heat the olive oil in a stock pot over medium-low heat. Add in the garlic, ginger, and mushrooms. Stir and cook until the mushrooms soften, about 3 to 4 minutes. Sprinkle with a pinch of salt and pepper.

Pour in the stock, water, sesame oil, and soy sauce. Bring the mixture to a simmer and taste the broth for seasoning. Adjust with a pinch of salt if needed.

Once the broth is simmering, add in the potstickers. Cook for 3 minutes (or longer, if the package directions call for it), until the potstickers are cooked through.

Serve immediately with extra scallions, soy sauce, sesame oil, and furikake seasoning for topping.
