Finely chop chorizo in a food processor or with a large knife. Gently mix together ground pork, chopped chorizo, breadcrumbs, egg, onion, green pepper, garlic and salt. Shape into 6 patties about 3/4-inch thick. Refrigerate for 10 to 15 minutes. Prepare a grill for direct cooking over medium-high heat, about 450 degrees F. Grill burgers, with the lid closed, for 5 minutes. Turn and finish cooking for 4 to 5 minutes more, until cooked through or until the internal temperature reads 160 degrees F on a digital meat thermometer. Remove from grill. Toast buns on the grill, about 1 minute per side. Build burgers on buns with 1 1/2 tablespoons dressing, 1/3 cup shoestring potatoes and one lettuce leaf. Serve immediately.
Try these burgers with a cool Caribbean-salad of marinated tomatoes and cucumbers with avocado chunks in lime vinaigrette.
