Preheat your Le Griddle over medium-low heat on one half and medium-high heat on the other.
To make the guacamole, combine all ingredients in a zip top bag and mash by hand.
Place a couple of tablespoons of beef tallow on the griddle over medium-low heat. When melted place the buns on the tallow to toast. When toasted flip and toast the outsides. Remove from the griddle.
Turn the heat up to medium-high.
Place a couple of tablespoons of beef tallow on one half of the griddle. When melted add the onions and jalapeño. Season with Cattleman’s Grill Mexicano Taco Seasoning. Cook, stirring and tossing occasionally until slightly softened and slightly browned.
While the veggies are cooking, place the ground beef on the other half of the griddle. Add the chipotles in adobo and season with Cattleman’s Grill Mexicano Taco Seasoning. Cook to brown then toss and stir. Add the pinto beans and mash the beans into the meat mixture with a potato masher.
Combine the veggies and meat and mix well. Remove from the griddle.
To build the taco burger, start by spreading the guacamole on the bottom bun. Top with shredded lettuce and diced tomatoes. Place a heaping 1/3 cup scoop of the ground beef mixture on the lettuce and tomatoes. Top with the shredded cheddar and a spoonful of Holmes Made Marty’s Roasted Green Chile Salsa. Place the top bun over the meat.
