Prep: Roughly chop cabbage, dice onion, mince garlic and thinly slice scallions.
Heat heavy skillet over medium heat. Saute onion in either olive oil, broth or water, until beginning to soften. About 2 minutes.
Stir in garlic, curry powder, salt and pepper. Cook, stirring constantly for about 30 seconds, until fragrant. If pan becomes dry, add 1-2 tablespoons water.
Stir in cabbage until thoroughly coated with spice mixture.
Mix in ¼ cup water. Cover and let steam for about 5 minutes.
Remove lid. Stir in edamame and allow to cook for about 2 more minutes, until edamame is heated through and cabbage is tender. Again, add up to 2 tablespoons water, as needed if pan has become dry.
Taste for seasoning, adding a pinch of crushed red pepper if not spicy enough for you. Sprinkle with scallions and serve warm.
Notes
Curry powder: If you don't have curry powder, mix together 1 teaspoon turmeric, 1 teaspoon cumin, ¼ teaspoon dried mustard, ¼ teaspoon ginger, pinch cayenne, pinch cinnamon.
