This is a main dish vegetable curry. Besides cauliflower it also has red potatoes and chickpeas. If you cannot find fire-roasted tomatoes, just use any diced tomatoes. Serve with na'an (an Indian flat-bread).
It couldn't be easier! Makes a nice side dish, or could serve as a main dish if you're in a vegetarian mood! Subtly sweet with just a hint of spice. Enjoy!
