A tweaked (actually, a very tweaked) version of a Hairy Bikers' recipe, which was their Cumberland Sausage, Chicken and Squash Tray Bake.
My tweaks were, firstly: Italian chilli and fennel sausage instead of Cumberland sausage, (because that was what was available in my fridge); sweet potato instead of squash (because that was what I had to hand); beer (German) instead of red wine (because I thought it would be interesting to see how it worked - however, as it happens, I do have plenty of both beer and wine), lots of garlic (not in the original recipe), and cherry tomatoes in lieu of mushrooms (because I had plenty of the former to use up, and none of the latter to hand).
Method: A roasting tin, drizzled with olive oil; sausages and chicken thighs (skin and bone attached, because that is where the flavour lies, and seasoned with sea salt and black pepper), placed in the roasting tin; a few onions roughly chopped and added; a few sweet potatoes peeled and roughly chopped and added; the lot drizzled with more olive oil, and seasoned with sea salt and freshly ground black pepper, and a generous amount of thyme, stripped from its sprigs. Simply because I like garlic, around eight fat cloves were peeled and sliced (roughly) and tucked under the chicken, sausages, onions, and sweet potato.
Some chicken stock was next added, followed by some German beer, and the lot found its way into a pre-heated oven (180C) where it will spend around half an hour before I remove it, add the chopped cherry tomatoes, some chilli flakes, check the seasoning, - and liquid - before returning it to the oven for a further half an hour or so before serving.
