In a mixing bowl, combine tahini, lemon juice, a drizzle of olive oil, and a splash of water. Whisk until smooth and creamy. Add water as needed to thin the dressing-it should be pourable but not too runny. Season with salt and freshly cracked black pepper.
1 ½ tablespoon lemon juice, 2 tablespoon tahini, 1 tablespoon olive oil, 1-2 tablespoon water, salt and pepper to taste
