Made this the other night and we really enjoyed. Very simple to make. I used the spaghetti and bacon as our local store doesn't carry the pancetta and bucatini. Also used mozzarella. I left out the green onion because I didn't have any. Will be making this again.
Used chopped shallots instead of the green onion (scallions) the 2nd time around. The shallots worked well too.
Made this for dinner tonight and it was very good. Easy to make for a week night meal after a long day at work. I made the recipe the way it is but think when I make it again I'll add some fresh garlic to the onion and pancetta. Thank for the recipe!
