Line a 9x13" glass baking pan with parchment paper. Preheat the oven to 350°F.
In a large mixing bowl combine all of the meatball ingredients (not the spaghetti or the pasta sauce). Mix with a wooden spoon or with your hands.
Break off tablespoon chunks of the meatball mixture and roll into balls. Place the meatballs on the parchment paper. You should be able to make 15-16 medium size meatballs.
Bake the meatballs for 20-25 minutes. The internal temperature should read 160°F.
While the meatballs are cooking, cook the spaghetti. Fill a large saucepan about half full. Bring the water to a rolling boil.
Add the spaghetti and cook for 8-10 minutes. Strain the spaghetti and add the 1 tablespoon of olive oil. Stir and cover until ready to serve.
In a small saucepan, heat the pasta sauce until it is warm.
Serve the cooked meatballs with the spaghetti and warm pasta sauce!
