Add garlic and oil to the crock pot. Note: If you have a sauce setting on your slow cooker. Sauté the oil and garlic together for about a minute until fragrant.
Then pour in the crushed tomatoes, tomato sauce, tomato paste and water.
Add cheese, sugar, herbs and seasoning. Give it all a good stir.
Cover and put crock pot on the low setting.
For the meatballs:
In a large bowl, combine all of the meatball ingredients. Shape into 12 meatballs.
In a large skillet, over medium-high heat, add a couple tablespoons of olive oil. Brown the meatballs on all sides.
Add meatballs to the sauce in the crock pot.
Cover and continue to cook with the sauce for about 6-8 hours (until meatballs are cooked through.)
Notes
When ready to serve, prepare your spaghetti according to package directions.
