Preheat your oven to 400°F/200°C (fan). In a baking dish or ovenproof skillet, whisk together ⅓ cup peanut butter, 1 tablespoon gochujang paste, 1 tablespoon sweet chili jam, 1 tablespoon soy sauce, 2 teaspoons fish sauce and coconut milk until smooth and creamy.
Scatter the edamame beans and chopped bok choy into the sauce and mix them through. Arrange the frozen dumplings snugly in a single layer in the sauce. You want them roughly half covered in the sauce to keep them nice and juicy in the oven.
Transfer to the oven and bake for 20 minutes, until the sauce is bubbling and the dumplings are cooked through. For a golden, crispy top, you can broil (grill) the dumplings for the last 3 minutes.
Drizzle the dumplings with the chili oil, then scatter with crushed peanuts, scallions, cilantro and crispy onions. Squeeze with a wedge of lime right before serving, and enjoy!
