Add in the tomatoes, ½ cup Hong Kong sauce and 1 tsp kosher salt, mixing to combine. Bring to a boil, then reduce the heat to a simmer. Let simmer for about 15-20 minutes, until the flavors have come together and the sauce has thickened. Meanwhile, preheat the oven to 375 degrees. Place bulgur in a large mixing bowl along with the remaining ¼ cup This Little Goat went to Hong Kong sauce, kale, chickpeas, lemon zest, gruyere cheese, Hong Kong tomato sauce and a pinch of kosher salt. Mix to combine and transfer mixture to a large baking dish or cast iron skillet. Cover with aluminum foil and bake until heated through, about 20-25 minutes. Remove foil and sprinkle with Parmesan cheese. Return to the oven and continue baking until the cheese is golden brown and bubbly, about 10 minutes more. Serve warm.
