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).
The easiest way to get your family to eat zucchini? Pair it with crispy, tender Parmesan chicken and pasta for a low-cal meal that they'll ask for again next week.
