On the subject of making your own...
Being a superior human being to most of you people on here, I always make my own.
But just in case anyone else is interested in crawling out of the primordial soup and making their own Italian-style breads too... Lidl did an "Italian week" last week, with plenty of items still available on the shelves. They do 100g sachets of dried tomatoes (which I much prefer to the jars of dried tomatoes soaking in vegetable oil) for £1.79 and 700g jars of green olives for £1.59.
I use these in focaccia breads and they're really lovely. Equivalent products in Tesco and Asda cost a hell of a lot more. The tomatoes are easy but unfortunately the olives have pips and because they're quite good, they can be a hassle to remove.
But focaccia with chunks of olive and sun dried tomatoes is absolutely delicious, especially with a good lasagne — home made from scratch, naturally. I'm reliably informed by those in-the-know that you can now buy lasagnes pre-manufactured by Super Markets, but I find the idea rather gauche...
