2.Heat remaining oil in a large non-stick frypan over a medium heat; add the garlic and red onion wedges. Cook, stirring, for 2 minutes. Add the kale and cook for a further 5 minutes or until the kale is soft and emerald green. Add the tomatoes and chickpeas, season with salt and freshly ground black pepper. Toss to combine; reduce heat to low.
