This is a vegetarian equivalent of keema (spiced mince lamb). It’s invariably cooked the same was as the lamb but for less time.
I minced half a cauliflower in a food processor to get a fine mince consistency. I heated a tbsp of Ghee with a diced onion, 3 cloves garlic and 1/3 inch ginger and cooked til brown. Added tsp salt, two of Garam masala and a tsp turmeric. Then added the cauliflower and cooked for 10-15 minutes in sealed pan. I added a chopped tomato and tsp purée about half way through. If it gets too dry or sticks to bottom of pan add some water to moisten.
