This is my take on a recipe from Giorgio Locatelli's remarkable "Made in Italy". It really is an Italian food Bible...
1 leek, sliced, sauted in butter until soft
3 rashers of bacon, cut into random pieces, fried until almost crisp
2 potatoes, peeled, cut into 1 cm cubes, boiled until just tender
1 handful of green beans, blanched for 2 mins, sliced (not too small)
2 tbsp pine nuts, toasted
1/2 large red chilli, diced
4 tbsp pesto
2 tbsp shredded parmesan cheese
Haloumi pieces, browned in a pan
Cook the leeks, beans, bacon and potatoes separately as above. Put them all into a frypan along with the chilli and pesto and 1-2 tbsp olive oil. Cook the pasta until it is 1 minute short of being ready. Right at the end, start to warm the bacon and bean mixture in the saucepan, stirring so that it doesn't burn. Add the fettuccine to the pan along with some of the cooking water from the pasta. Add the pine nuts and parmesan cheese and stir it all together. Serve with some of the haloumi on top and some parsley as garnish (I added marjoram which was just wrong...)
I never put beans and potato in pasta, but this was just great.
