1 pound 90%-lean ground beef
3/4 cup chopped fresh cilantro, divided
1/2 cup finely chopped red onion
1/4 cup chopped scallions
2 teaspoons minced garlic
1 tablespoon chili powder, preferably New Mexican
1 teaspoon ground cumin
1/2 teaspoon dried oregano, preferably Mexican
1/2 teaspoon freshly ground pepper
1/4 teaspoon salt
1/3 cup mayonnaise
1 tablespoon lime juice
1 tablespoon chopped chipotle chile in adobo, or other spicy chili pepper
1/2 cup shredded Monterey Jack cheese
4 French rolls, preferably whole-wheat, split and toasted
2 roasted Anaheim or poblano peppers
1 cup shredded green cabbage
4 slices tomato
4 thin slices red onion
Preheat grill to medium-high.
Place beef, 1/4 cup cilantro, onion, scallions, garlic, chili powder, cumin, oregano, pepper and salt in a large bowl. Gently combine, without overmixing, until evenly incorporated. Form into 4 equal patties, about 1/2 inch thick and oval-shaped to match the rolls.
Combine the remaining 1/2 cup cilantro, mayonnaise, lime juice and chipotle in a small bowl.
Peel the roasted peppers, halve lengthwise and remove the seeds.
Oil the grill rack (see Tip). Grill the burgers until an instant-read thermometer inserted in the center registers 165°F, about 6 minutes per side. Top with cheese and cook until it is melted, about 1 minute more.
Assemble the burgers on toasted rolls with the chipotle mayonnaise, half a roasted pepper, cabbage, tomato and onion.
