In a large skillet, heat the olive oil and brown the sausage. Add the crushed tomatoes, garlic powder, basil, oregano, onion powder, salt and pepper to taste. Bring the sauce to a boil, promptly reduce the heat and allow it to simmer for 10 minutes.
Add the sauce to the slow cooker insert. Stir in the olives, drained capers, and white wine.
Note: you could substitute a 26 oz. jar spaghetti sauce in place of the homemade tomato sauce listed above.
Set on low and cook for 8 hours. If your slow cooker runs hot or overcooks or dries out other meals, add 1/2 cup water.
Just before dinner, cook the pasta. Drain well.
Prepare the veggies.
Serve Slow Cooker Puttanesca Sauce over pasta with side of veggies.
