Heat a soup pot to medium and add oil to pan. Add garam masala and cumin and stir for 30 seconds. Add garlic, onion, and cauliflower plus a good pinch of salt and some pepper. Stir regularly until onions are soft - about 10 minutes.
Add wine and cook down for a minute or two. Add stock, cover, and bring to a simmer.
Cook until cauliflower is very tender, 15-20 minutes.
