Ultimate Burger Stack: Two ½ lb Beef Patties, 4 Slices Extra Sharp Cheddar & Swiss Cheese, Bacon, Red Onion, Tomato, Lettuce and Pickles on an Onion Bun Ken didn’t want a big burger for our date night. He wanted a BIG burger! We made this one just for fun. This beefy beauty was two ½ lb. burgers made extra special with Zaycon Fresh ground beef. Because Zaycon Fresh is 93/7 super lean ground beef there’s no fillers or additives meaning little shrinkage and all natural true beef flavor. Plus, because it comes in a 10lb. chub we just cut our patties to whatever thickness wanted. We added two kinds of cheese each: one slice of extra sharp cheddar and one slice Patti’s favorite Swiss. Of course, we had to add lots of crispy bacon and Cattleman’s Grill Original Cowboy Seasoning with just a spritz of Worcestershire sauce on a big onion bun. Side dishes were not needed.
