"Create a metric recipe for an Indian-style spiced cauliflower dish based on the user's provided ingredients and method. Make it a clear, polished recipe with a title, ingredient list in metric units, step-by-step instructions, serving suggestions, and optional variations. Keep it vegetarian and vegan-friendly. Use a medium cauliflower head, onion, garlic, ginger, tomatoes, cumin seeds, turmeric, coriander, garam masala, vegetable oil, salt, and cilantro. Aim for a flavorful dry-ish cauliflower curry/sabzi suitable with rice or naan."
