Preheat large dutch oven or heavy bottom pot on high heat and add ground beef and turkey. Cook breaking into small pieces and stirring with spatula constantly, for about 5 minutes.
Add onion, garlic, oregano, basil, thyme, cinnamon, salt and pepper. Cook for about 2 minutes , stirring a few times. Please note onion doesn't need to brown but herbs benefit from high heat to release maximum flavors.
Add olive oil, balsamic vinegar, maple syrup, diced tomatoes, tomato sauce, tomato paste and bay leaves. Stir, cover and cook on low-medium heat for about 30 minutes. Covering the pot prevents red splatters all over the stove.
Open the lid a little bit to the side and cook for another 15 minutes. Moisture will evaporate making perfect hearty and thick meat sauce.
Stir and serve hot over whole grain spaghetti or any tubular pasta, garnished with freshly grated Parmesan cheese.
