Place a skillet over medium heat and add the oil. When it is hot, add the garlic and ginger and cook for 2 minutes. Add the coriander, fenugreek, paprika, salt and pepper and cook for 30 seconds. Add the Brussels sprouts and 1/2 cup water and cover with a tight-fitting lid. Let steam until the sprouts are bright green and tender-crisp, 6 to 8 minutes.
