Throwing a load of vegetables in a tin with some herbs, oil, salt and pepper is about as easy as cooking gets. Easier than boiling an egg, even. It's a great accompaniment to roast meat and steamed fish and gets a load of different colours on your plate. I love picking out the caramelised, sticky and juicy bits that have caught in the pan while roasting, it's such a comforting and delicious treat that the cook gets all to their sneaky self.Often I'll roast a chicken or joint of pork on top of the veg, that's a real treat. The meat takes on a deep flavour, and the juices in the pan are so rich and delicious, you just pour them over, there's no need to make a sauce.I've even roasted a load of sausages in among the vegetables, a perfect one pot meal. All it takes is a little peeling and chopping then the oven does the rest. You can throw in some tomatoes too, they give off their juices and mingle deliciously with the other veg. Fennel softens beautifully, giving off its light, mellow aniseed to the pot and onions turn golden, sticky and sweet.Use what is available at the time and keep an eye on it while cooking so it doesn't burn. 35-45 minutes at 180c is normally about right, depending on what veg you use. One tip I'd give is to have the more delicate vegetables at the bottom and harder ones such as beetroot, carrots and the like on top.Drizzle everything in olive oil and season well with salt and pepper. Mix through some hardy herbs such as rosemary, sage and bay leaves and finish off with some young thyme and perhaps chilli flakes as it comes out the oven. Put it straight on the table and dig in.
