In a small bowl, mix the 2 tablespoons chili powder, 1/2 teaspoon garlic powder, 1/2 teaspoon onion powder, 1/2 teaspoon crushed red pepper flakes, 1/2 teaspoon dried oregano, 1 teaspoon cayenne pepper, 2 teaspoons cumin, 1/2 teaspoons fine sea salt1 teaspoon black pepper2 teaspoons ground coriander, Set aside. *See note
In a large bowl, tear apart the 1 pound ground beef into smaller bits. Toss gently with the spice mix (or taco seasoning).
Divide the ground beef into fourths. Hand form 4 large patties and then make a well in the center of each. Evenly divide hot sauce on the tops of each patty. Arrange on a plate and place into the freezer for 10-30 minutes.
Heat the grill to medium-high heat. Grill the hamburger patties for 2-3 minutes per side on direct heat, then remove to indirect heat until desired doneness. For the last minute, add a slice of pepper jack cheese to each patty.
Remove from the grill and allow to rest for 5 minutes before assembling.
To build the burger, place the patty on a Kaiser Roll, top with pico de gallo, avocado, sour cream and jalapenos.
