In a large skillet, heat the olive oil on medium-high heat. Add the sunchokes and sprinkle with salt and pepper. Sauté for 5 minutes, flip and saute until tender and brown on both sides, about an additional 5 minutes.
While the sunchokes are frying combine all the ingredients in a blender or food processor. Blend until the sauce is very smooth. Add more water if necessary to thin out the sauce.
Spread the tahini sauce on the plate and top with the sunchokes. Garnish with chopped fresh herbs.
For softer sunchokes soak in water and heat in the microwave for 3 to 4 minutes before sauteing.
