Pasta with sausage and greens

It's a rush blog this week, so you get a recipe.  Because that's quick and easy.  And so is cooking this.

Pasta is a problem in our house.  Well, not so much the pasta, as what to put on it.  Graham doesn't like creamy sauces, and Toby isn't that keen on tomato ones, so that kind of leaves... pesto.  Or recipes like this where you just stir all the bits into the pasta, and it somehow has enough flavour and juiciness not to need a sauce.

Pasta with sausage and greens
200g pasta
1 lb sausages
1 onion, sliced
50-100g spring greens / kale / whatever, sliced
1/4 tsp dried thyme
6-8 cherry tomatoes, halved or quartered, depending on size
1 tbsp balsamic vinegar

Cook pasta and drain, reserving a little of the cooking water.
In a large pan, fry the sausages.  When cooked, remove from the pan and slice on the diagonal.
In fat from sausages, fry the onion until soft, about 5 minutes.
Add the greens and thyme and cook 3-4 minutes more.
Add the tomatoes and sausage to the pan, and just let warm through.  You don't really want the tomatoes cooked, just not stone cold.

at which point it looks like this

 Stir in the cooked pasta and vinegar, with a splash of pasta water to moisten it all up.
As usual with my recipes, this serves two hungry adults plus a couple of small boys, but it's the kind of thing that is nice for lunch the next day too.
