Preheat oven to 220˚C / 425˚F.
Place the brussels sprouts on a baking tray and drizzle with olive oil. Scatter with sea salt and black pepper and roast for 20-22 minutes until golden and tender.
Meanwhile, make the hot tahini sauce, place the tahini, hot sauce, salt, black pepper and lemon juice in a bowl and whisk to combine (it will become too thick to stir). Add ¼ cup of water and whisk until smooth. If it’s too thick, add more water, a tablespoon at a time, until it is a thick, pourable consistency.
Shake off any excess water from the lettuce and wrap in a large, clean kitchen towel to absorb any excess water. Cut the dates into thin slices.
Place the lettuce onto a large platter or serving plate. Top with brussels sprouts and add a few dollops of the hot tahini. Give it a light toss and then scatter over the dates and sesame seeds. Drizzle with olive oil, and give it a final season of sea salt and black pepper. Squeeze over the lemon juice and serve.
