Serve this broccoli as a side dish or as a first course in place of a salad.
In a small bowl, mix miso, sesame seeds, lemon juice, and oil. Slowly add the milk, stirring well. For a thinner sauce, add more liquid.
Arrange broccoli florets in a steamer basket over a small amount of water. Steam florets until bright green and just tender, about 5 minutes.
Transfer to serving dish; drizzle with sauce and garnish with red pepper.
