  In small mixing bowl using a fork or whisk, beat the egg. Whisk in the milk and Worcestershire sauce. Stir in the bread crumbs and Cajun Rub and let the mixture sit for 5 minutes.

  In another bowl, combine the ground beef, onion, garlic, and black pepper. Add the egg mixture to the meat mixture and combine well.

  If the mixture seems dry, add a bit more milk. If wet, add a few dry breadcrumbs. Roll the mixture into balls about the size of golf balls.

  When ready to cook, set the Traeger to 325℉ and preheat, lid closed for 15 minutes.

  In the meantime, heat the jarred marinara in a pan on the stovetop. Transfer the cooked meatballs to the pan and let them simmer for 5 to 10 minutes.

  Tear off four sheets of aluminum foil and lay them on your work surface. Put a hoagie roll in the center of each. Divide the meatballs among the rolls.

• 8

  Top the meatballs with provolone cheese. Wrap the sandwiches tightly in the foil and return to the grill to heat, 10 to 12 minutes.
