Heat the olive oil in a saucepan over medium heat and cook the onion and turkey bacon until the onion is soft and translucent, and the turkey bacon is lightly browned (this takes about 6 minutes)
Add the white wine and tomato paste. Stir and cook for 1 minute until the alcohol evaporates.
Add the whole tomatoes. Crank the heat up to high until the sauce starts to boil, then turn the heat down to medium0low and let the sauce simmer, uncovered, stirring occasionally for about 15-20 more minutes. Break up the tomatoes with your spatula as you stir.
Meanwhile, while the sauce is simmering, boil a pot of water and cook the spaghetti according to package instructions.
Drain the spaghetti. Stir the sauce, grated Parmesan cheese and spaghetti together (I put a little extra grated Parmesan on mine.)
