Wash and slice the Mushroom (250 gram), dice up the Firm Tofu (125 gram) into half inch cubes, and wash and cut in the Red Chili Pepper (2) in half, length-wise.
Bring a pot of Water (3 cup) and Coconut Milk (1/2 cup) to a boil, then add Red Miso Paste (1 teaspoon), mushrooms, tofu, and chili. Add salt and pepper, as desired. When water is boiling again, add the Flat Rice Noodles (200 gram) and cook for 5 minutes.
Divide soup into bowls and serve with some Fresh Cilantro (to taste) on top. Serve warm.
