This is a simple, quick and easy main dish for salmon spaghetti carbonara. It's the perfect use for leftover cooked salmon. If there's any left over from this dish, make cheesy pasta frittataI've made this recipe with spaghetti, fettuccine, and linguine pasta; it's delicious with all three. Any long pasta is perfect in this dish; it holds onto the creamy sauce and is the perfect foil for the tender salmon and salty bacon. Make sure you serve this wonderful dish as soon as it is served. The sauce will thicken as it cools, and you want to make sure your guests get the combination of tender pasta, nutty salmon, crisp and salty bacon, and smooth and creamy sauce.
