Perfect for a lazy cold afternoon. It is (and looks) full of calories but at least you are getting some vegetables in.
2 carrots, 1 large onion and 2 sticks of celery cut in small cubes (alternatively you can buy this at the supermarket in the prepared vegetables section - it is called 'sofrito')
1 tin of chopped tomatoes (in their natural juice)
a tbspoon of creme fraiche (optional)
4 slices of cheese (mild cheddar, edam, gouda, or equivalent)
Preheat the oven at 220 degrees. Put the vegetables on a baking tray, add the salt and cook them in the oven for 15 minutes. Then add the sausages and put them back in the oven for around 25-35 minutes or until they start getting golden on one side (this really depends of how thick the sausages are). Turn around the sausages to the other side, add the tomato of top (mixed with the creme fraiche if you are using it) and put it all back in the oven for another 20-25 minutes (until the sauce gets a bit thick). Just before serving the dish, put the cheese on top of the sausages and put it all under a hot grill for a couple of minutes (until it all gets dark golden).
Serve with pasta, or beans or just on its own.
Kids can do most of this but you need to supervise them really closely and help them to get the tray in and out of the oven as it does get dangerouslyy hot.
