Sausages baked with squash, tomatoes and pasta recipe

This is the most delicious baked pasta dish and takes a fraction of the effort required to make lasagne. I have been sceptical about one-pot pasta dishes – it feels odd to put dry pasta in a casserole – but this works (I continue to be amazed that it all comes together). It’s a big, cheerful, ‘friends-and-family-round-the-table’ meal.
