Method
Step 1
Heat oven to 450°F. In bowl, combine scallions and seeded jalapeños, 1/4 cup cilantro (chopped) and lime zest, then toss with Monterey Jack cheese.
Step 2
Insert knife into thickest part of each of boneless, skinless chicken breasts and move back and forth to create 2 1/2-inch pocket that is as wide as possible without going through. Stuff chicken with cheese mixture.
Step 3
Heat 2 tablespoons olive oil in large skillet on medium. Season chicken with salt and pepper and cook until golden brown on 1 side, 3 to 4 minutes. Turn chicken over and roast until cooked through, 10 to 12 minutes.
Step 4
Meanwhile, in large bowl, whisk together lime juice, 1 tablespoon olive oil and 1/2 teaspoon salt. Add bell peppers and red onion and let sit 10 minutes, tossing occasionally. Toss with romaine lettuce and 1 cup fresh cilantro. Serve with chicken and lime wedges.
