Preheat oven to 400F. Cut the broccoli florets down into chunks, leaving the stems long. Add broccoli, olive oil, and 2 hefty pinches of salt to a tinfoil lined baking sheet and toss. Bake for 30 minutes or until brown and crispy on the bottom.
Meanwhile, make the sauce. Add tahini, warm water, olive oil, garlic, mint, cilantro, dill, and the juice from 1 lemon to a bowl and whisk. Season with salt to taste. Set aside.
After the broccoli is done roasting, remove it from the oven. Smear half of the tahini sauce onto a plate and top it with the broccoli - creating a dome like shape. Spoon the rest of the tahini sauce on top and finish with fresh lemon zest before serving!
