Heat the oven to 220 Degrees, then dice up the onion and pepper and cut the florets off the broccoli. Cook the chickpeas in a hot pan for 8-10 minutes, then drain and add to a large bowl, along with the other chopped vegetables. Next, add the oil and soy sauce, mix together and then add all the spices – give these a good stir so they’re well marinated, and then pour it all into an oven proof dish and bake for 20 minutes.
