Green Chile Cheeseburgers

1. Heat grill to high. Form meat into 4 (8-ounce) burgers and season each burger on both sides with 1/4 teaspoon of salt and a 1/4 teaspoon of pepper. Grill until charred on both sides and cooked to desired doneness.
2. Place 2 slices of the cheese on each burger, close the lid or tent with foil, and cook until the cheese has just melted, about 1 minute. Place burgers on buns and top with a few tablespoons of Green Chile Sauce and lettuce, tomato, and pickled jalapeno, if desired.

Green Chile Sauce:

1. 2 poblano chiles, grilled, peeled, seeded, and chopped
2. 1 medium white onion, grilled and chopped
3. 1 to 2 cloves garlic, chopped
4. 2 tablespoons chopped fresh epazote, or fresh oregano leaves
5. 1/4 cup cold water
6. 1 tablespoon honey
7. 1/4 teaspoon kosher salt
8. 1/4 teaspoon freshly ground black pepper
9. Place all ingredients in a blender and blend until smooth. Season with salt and pepper, to taste.
