Cook cauliflower in pan filled with boiling water for 20minutes.
While cauliflower cooks, chop all vegetables and crush garlic.
Drain cauliflower after 20minutes and add to a Wok with other vegetables.
Add curry sauce(because I'm too lazy to cook the sauce from scratch).
Allow to cook on low heat for 10-15 minutes. This is when you should cook the rice or whatever you plan to accompany the curry.
Just before removing the curry from the heat add the prawns and allow to warm through but for no longer 3 or 4 minutes as the prawns will go rubbery.
Serve with rice, chips or just naan bread and poppadums....your choice.
