Heat a large pot over medium. Add the sesame oil and let it warm until it smells nutty, about 30 seconds.

Add the minced garlic and grated ginger. Sauté, stirring, until fragrant—about 30 to 45 seconds. Don’t let the garlic brown.

Pour in the vegetable broth and bring the liquid to a gentle boil.

Add the potstickers to the boiling broth. If they’re frozen, simmer for 6–8 minutes or follow the package directions until heated through and the wrappers are tender. If using pre-cooked or freshly pan-seared potstickers, add them to the broth and simmer for 2–3 minutes to warm through.

Add the greens and the soy sauce. Stir and let the greens wilt for 1–2 minutes. Taste and adjust seasoning with salt and pepper.

Ladle the soup into bowls and garnish with sliced green onions. Serve immediately while hot.
