Prepare Dashi (optional) Heat 2 cups of water. Add bonito flakes or kombu, simmer for 5 minutes, then remove. (Skip this step if using only Minute Miso.)
Stir the Minute Miso packet into the hot water. Optionally, add 1-2 teaspoons of fresh miso paste for deeper flavor.
Toss in the tofu cubes and wakame seaweed, letting the seaweed rehydrate for 2-3 minutes.
Stir in sliced mushrooms, daikon radish, or carrots, and cook for 2-3 minutes until tender.
Top with chopped green onions and sesame seeds. Add shichimi togarashi or chili oil for a spicy kick, if desired.
