Roasted And Raw Broccoli Salad With Creamy Miso Dressing

Using a hand blender fitted with the whisk attachment, whisk soy sauce, tahini, miso, fish sauce, sesame oil, sugar, ginger, and 2 Tbsp. lemon juice in a small bowl until smooth.
Whisk egg yolk and remaining 2 tablespoons lemon juice in a medium bowl to combine. Stream in 1/2 cup vegetable oil, whisking constantly until mayonnaise is emulsified and thick. Still whisking constantly, gradually add soy sauce mixture, then remaining 1/4 cup oil. Season with salt and pepper. Set aside until the salad is assembled, and you'll definitely have extra dressing for other salads.
Set the oven to 400u0b0F. Chop the stem off the broccoli but don't get rid of it! Set it aside for just a bit. Chop up the broccoli florets into bite-size pieces. Use a hand blender to chop 3 to 4 of florets until they reach a crumb-like consistency. Set this mixture aside, reserving their little stems to use later, and spread out on a parchment paper-covered baking sheet. Toss with olive oil and roast for 15 minutes.
While the florets are roasting, shave with a peeler the fat broccoli stems and as much of the smaller stems as you can. When finished roasting, remove the florets from the oven.
In a large, low bowl, make a bed of shaved broccoli stems and toss with the roasted florets. Drizzle as much or as little dressing on top as you'd like, and top with crumbled florets, a smattering of sesame seeds and chopped salted peanuts.
