Cauliflower in Tahini Sauce

• 1 large cauliflower, broken into florets
• 3 garlic cloves, crushed
• 1 heaped tablespoon tahini

Steam the cauliflower briefly, or boil in a little salted water until just tender, but al dente. Meanwhile, make the sauce. Crush the garlic into the tahini and add the lemon juice, zest, water and seasoning. Stir until you have a thick sauce. Drain the cauliflower carefully, arrange in a serving dish and pour the sauce on top. Sprinkle with sesame seeds.
