Slow Cooker Spaghetti and Meatballs

This is one recipe I plan to make again. I grabbed it from Canadian Living.

Spaghetti and Meatballs

Ingredients
1 Tbsp olive oil
1 onion, chopped
garlic
1/2 tsp oregano
salt
1 can crushed tomatoes
1/4 cup minced fresh parsley (I just omitted this)
1 lb spaghetti, cooked

Meatballs
1 egg
1/2 cup onion
garlic
1/4 cup each breadcrumbs (or use crushed crackers) and Parmesan cheese
1/2 tsp each basil, oregano, salt, pepper
1 lb ground beef

Meatballs: Mix all except meat, then mix in beef. Shape into 16 balls. Bake 400F on foil lined sheet for 10 minutes. Put in slow cooker.
Meanwhile: In skillet heat olive oil over medium heat and cook onion, garlic, oregano, salt, stirring occasionally till onion is softened, about 5 minutes. Transfer to slow cooker.
Stir in tomatoes. Cover and cook on low 4-6 hours. Add parsley. Serve with spaghetti (and toast and salad).
