An easy, all-in-one chicken traybake for a casual dinner with friends, packed with flavourful vegetables. Rather than a long list of spices, I like to use ras-el-hanout for this. It’s a readily available Middle Eastern spice mix that adds a lovely warming flavour to the dish. It isn’t hot in the way that chilli is, so if your guests like spicy food, add a teaspoon of chilli flakes as well.
