What to do with a box of tomatoes. Turn them in to pasta sauce. While I was out and about yesterday I came across a large box of tomatoes in the fruit shop. 12 jars later and I now have a supply of Tomato Pasta Sauce in the cupboard. They have all been preserved nicely in a water bath so no nasties can get into them. Lovely homemade sauce instead of supermarket bought ones. Quite proud of my achievement this weekend.
