COOK IT.
Preheat grill to 150. -In a large mixing bowl, add in ground beef, egg, and seasonings. Mix thoroughly. -Spread out the ground beef onto a silicone grill mat (wax paper will work fine). Spread it out as evenly and thin as you can into a rectangular shape. -Spread the chopped mushrooms, onions, cilantro, and cheese evenly onto the ground beef. You will be rolling this up like a sushi roll, so even ingredients is key.
Use the silicone grill mat to slowly roll one side of the meat and continue until the entire rectangle is rolled tight. -Spread the chopped garlic pieces across the silicone mat and roll the meat log across it so the chopped garlic pieces are spread over the log. -Place the meat log on the silicone mat inside your smoker at 150 degrees for 2-3 hours until the internal temperature reaches 110 degrees.
