I keep a couple of bags of the shredded leek-and-carrot mix in the freezer; I find it to be so much less hassle to do a big session of chopping once in a while than to have to start knife work every single time! A couple of handfuls of the mixture is enough for one batch of soup and defrosts ever so quickly - I suspect that you could probably could use it straight from frozen, but I've never tried. **UPDATE: I now have, and you can! **
Bean & Bacon Soup with Small Pasta
I generally use macaroni, as I keep that in the storecupboard as a matter of course; you can always substitute another small 'soup' pasta (like conchigliette), or just use some broken-up bits of spaghetti. This amount feeds all four of us comfortably, with enough left over for two small portions for lunches in the week. It freezes well, too.
1 leek, halved and sliced
2 carrots, diced
1.5 litres chicken stock
2 tbsp pesto
150g small pasta (and see above)
2x 300g cans borlotti beans, drained
Grated parmesan, to serve
Heat a very little oil in a large pan. Fry the bacon until cooked and tinged with brown. Scoop the bacon out of the pan and set aside. Put the leek and carrot into the pan and fry until soft. Add a little of the chicken stock and scrape up all the nice toasty bits that have 'caught' on the bottom of the pan, then put the bacon back in the pan, pour in the rest of the stock and bring to the boil. Add the pesto and stir well, then tip in the pasta and cook for five minutes. Add the beans and continue to cook until the pasta is al dente. Ladle into warm bowls and serve, topped with plenty of freshly grated parmesan.
