In a large bowl, mix the ground beef, sausage, bread crumbs, eggs, onion, garlic, Italian seasoning, salt, and paprika. Mix until very even and smooth.
Set a large nonstick skillet over medium heat. Roll the meat mixture into tight ball, 1 1/4-inch wide. Place them in the skillet and brown on all sides.
Once the meatballs are cooked on the outside, move them to 4 quart slow cooker. Continue rolling and browning until all the meatballs are in the slow cooker.
Pour in the cranberry sauce, pepper jelly, and barbecue sauce. Cover and set on low for at least 3 hours, or on high for at least 1 1/2 hours.
Set the slow cooker on warm until ready to serve.
