Preheat the oven to 375ºF.
Make the sauce. In the bottom of a 9x13 baking dish, whisk together coconut milk, diced shallot, grated ginger, Thai red curry paste, soy sauce or tamari, rice vinegar, coconut sugar, fish sauce, and toasted sesame oil.
Add greens. Add the chopped spinach and give it another whisk.
Add dumplings/potstickers. Place the frozen dumplings on top of the sauce and spinach mixture then spoon some of the sauce over the top of the dumplings.
Bake. Cover with foil and bake for 20 minutes. Uncover and bake an additional 5-10 minutes, until the sauce is bubbling and dumplings are tender and lightly golden brown on the outside.
Garnish. Top with sliced green onion, chopped cilantro, and sesame seeds. Enjoy!
