Make the whipped tahini. In a food processor, combine the tahini, garlic, lemon juice, date syrup, olive oil, and sea salt. Pulse until the garlic is finely chopped. Then, with the motor on low, drizzle the water in through the feed tube. Stop the food processor to scrape down the sides and pulse it a couple more times. The resulting texture should be a thick, somewhat whipped-like texture, but still fluid enough to pour off of a spoon. Once you have it right and seasoned to your liking, set the whipped tahini aside in the fridge in a container.
Set a medium skillet over medium high heat and pour in the olive oil. Once the oil is hot, add the dried chili and stir it around for 30 seconds or so. Then, add the chopped hazelnuts. Fry the hazelnuts, stirring constantly, until they are slightly darkened and very toasty smelling, about 2-3 minutes. Remove the skillet from the heat. Transfer the hazelnuts to a paper towel-lined plate, reserving as much of the infused oil in the skillet as you can. Set aside.
Return the skillet to the stove and set it to medium heat. You should still have at least a tablespoon of olive oil (and the dried chili!) in there. If not, add some more olive oil. Then, place all the broccolini in the skillet. Let it sear on one side for 2 minutes. Then, using tongs, flip the pieces over and let them sear for another 4-5 minutes or so, giving the pan a shake here and there. Season with salt and pepper.
Once the broccolini is seared on both sides and starting to look bright green, pour in a splash of water and place a lid on top. Let the broccolini steam until the thickest parts of the stalk are tender, about 3 minutes. Remove the lid and sprinkle the broccolini with the lemon juice. Remove the broccolini from the heat.
To serve: Spoon ¾ of the whipped tahini onto the center of your serving plate. Spread it out evenly with the back of a spoon. Then, scatter the wheat berries evenly over the surface of the tahini. Then, place the seared broccolini on top. Finally, garnish the dish with the fried hazelnuts, a few extra dabs of date syrup (if you like), and a few twists of black pepper. Serve immediately.
