Fiesta Burger

1 pound ground beef
4 ounces chorizo sausage, casing removed
2 teaspoons onion powder
1 teaspoon ground cumin, plus 1 teaspoon for sauce
Salt and pepper
1 cup grated aged Cheddar
1 cup queso blanco
1/2 cup mayonnaise
1/4 cup ketchup
1 lime, zested and juiced
6 slider buns, split

In a medium bowl, mix together the ground beef, chorizo, onion powder, cumin and 2 teaspoons each salt and pepper. Form the mixture into palm-size balls.

Heat a griddle or large skillet over medium-high heat. Place the balls on the griddle and smash with a spatula or the back of a spoon. Cook, flipping once, until cooked through. Divide the Cheddar and queso blanco among the burgers and let melt. Remove the burgers to a plate.

Meanwhile, combine the mayonnaise, ketchup and lime zest and juice in a bowl; mix to blend. Add cumin, salt and pepper to taste.

Toast the slider buns on the griddle. Serve the burgers on the buns, topped with some rosada sauce.
