Yes, similar to smoked meatballs, you can substitute half the ground beef with ground pork. This recipe can also be adapted to use ground chicken meat or ground turkey meat. All these meatloaf smoker recipes are variations you can make based on this Sip Bite Go version. They have all turned out great and full of flavor in my experience. But, I do have to say, the poultry versions in particular can be a bit softer and more likely to fall apart compared to beef.
