Tray bakes go down well here. There are huge number of variations but we enjoy paprika chicken, sweet potato, red onions and peppers and garlic. Sausage, parsnip, carrot, apple, shallots with sage. Salmon, new potatoes, asparagus and tenderstem broccoli with lemon wedges. Add the green veg towards the end. Chicken, cauliflower, red pepper, chickpeas with various spices.
