Lemony Cauliflower Curry with Sumach

"Curry to me is a dish for all seasons, but I know people who prefer eating it rather during the colder months. With this lemony cauliflower and zucchini curry, you’ll have a dish that you can enjoy during the warmer months too, as it tastes fresh and vivid thanks to the special citrusy quality of sumach, kaffir lime leaves, and lemon slices. I like to serve the curry with brown rice as it brings a complementary depth and earthiness to the fresh lemony taste of the vegetables."
