Meatballs with Roasted Red Pepper Sauce

I've had this recipe for years, its one of the kids favorites. My mother in~law made for Sunday dinner once. It's so easy. Even easier with the slow cooker liners that are available now.

1 1/2 lbs frozen meatballs
1 jar roasted red bell peppers, drained
1/4 cup grated parmesan cheese
1/4 cup Italian dressing
1 jar marinara sauce

Place meatballs in slow cooker. Place bell peppers in blender cover, and blend until smooth. Add rest of ingredients and blend until well mixed. Pour sauce over meatballs. Cook on low for 6-7 hours. Serve over hot noodles, or we really like it over rice.
