Mix together the beef and chorizo, sprinkling with salt and pepper. Form 4 patties, each around 6 ounces.
Blend the jalapeno with the mayonnaise to make a jalapeno aioli. Transfer to a bowl and set aside.
Make a pico de gallo by combining the tomatoes, red onion, cilantro, lime juice, salt, pepper and cayenne to taste.
Grill the burgers until well done, around 5 minutes per side. Top each with a slice of pepper jack cheese. Grill the buns.
Build the burgers by spreading a layer of jalapeno aioli on the bottom bun, followed by a slice of lettuce, the burger, some pico de gallo and finally the top bun with more aioli.
