This is so simple to make with only a handful of ingredients which we would normally have on hand, except maybe for the speck but bacon could be substituted.
I made half the recipe which would only be 2 small serves for me. You could make it go further by using it as a side with a piece of meat though.
I used tasty cheese instead of Fontina, used bow pasta instead of shells and cooked the speck in a frying pan before adding it at the end. The thought of adding fatty speck to the dish with 2 minutes to go didn't appeal to me at all and frying it had to increase the flavour. Each time I had a piece of it in the pasta it gave me an amazing hit of flavour and for that reason I would add more speck next time.
Well worth making.
