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.
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.
