This is my own varient where I use the slow cooker. It's SO tasty and easy and goes amazing with any kind of pasta.
3 14oz cans diced tomatoes (with or without basil, oregano, and garlic)
2 14oz cans artichoke hearts drained and quartered
4-6 cloves garlic (minced)
1/2 cup whipping cream
Italian seasonings (basil, oregano, parsley ect) and salt and pepper to taste
a drizzle of olive oil
Add oil and garlic to the slow cooker (on high) and stir until heated. Add two cans of tomatoes (drained), the remaining can (undrained), the artichoke hearts, and the seasonings/ s+p.
Cover and cook on low (6-8 hrs) or high (3-4 hrs).
Stir in whipping cream and let heat through.
While it's heating, cook pasta, then dish up. It goes really well with a little parm on top! :)
