Preheat the oven to 400°F.
In a bowl, mix the coriander, paprika, five spice, soy sauce, and oil.
Brush the mixture onto both sides of the wedges.
Heat a cast-iron skillet, or other oven proof pan, over medium heat. Add a thin layer of oil to the pan. When hot, add the cabbage wedges and cook, not moving, for 5 minutes per side, or until well seared.
Pour the vegetable broth over the top of the cabbage wedges and put the pan in the oven. Bake for 15-20 minutes, or until the cabbage is tender.
In a bowl, combine the soy sauce, sambal oelek, pepper, five spice, maple syrup, and chili oil. Whisk until smooth.
When the cabbage is done, transfer it to a serving platter. Pour the sauce evenly over the wedges. Top with the crushed peanuts and green onions.
