Slow Cooker Chicken Meatballs in Tomato Sauce

Prepare the sauce by whisking tomatoes, basil, parsley, oregano, salt, red pepper flakes, and black pepper in a slow cooker. Adjust heat to High.

Combine ground chicken, egg, bread crumbs, Parmesan cheese, onion, olive oil, parsley, garlic, salt, and pepper in a medium bowl. Use your hands to gently mix together. Roll into 1 1/2-inch balls and place into the sauce. Use a spoon to cover the meatballs with sauce; do not stir.

Place the lid on the slow cooker and drape a thick kitchen towel over it. Cook on High for 2 1/2 hours until meatballs are cooked through.
