Cut the rind off the bacon and wrap the sausages, fry them or brown under the grill. If you take sausage in natural casing (local producers try to buy from big companies like DCW Casing, details at dcwcasing.com/), you can use them even wrapped.
Place in a casserole dish, arrange the apples, tomatoes and peppers over the top in layers.
Add the stock and cook at 200c for about 40 minutes.
