In a frying pan cook the ground beef until there is very little pink left. Add the onion and garlic. Sauté until the onion is just starting to become tender and translucent.

In a bowl mix together the spaghetti sauce, tomatoes, olives, water, Italian seasoning, salt, pepper and parsley.

In the slow cooker pot add half the cooked beef mixture. Break the spaghetti noodles into thirds and spread them over the beef mixture. Be sure to spread them around, if you leave them together they will cook in clumps!

Pour the rest of the beef mixture over the noodle pieces. Then pour the spaghetti sauce mixture over all of this. Top with the cheddar cheese.

On the Low setting on your slow cooker cook for 3 hours.

The slow cooker spaghetti is done when the noodles are tender.
