Heat 1 tablespoon olive oil in a medium size pot over high heat. When the oil shimmers, add the chicken and season with salt and pepper. Cook until seared on both sides, about 3 minutes per side. Add the poblano pepper and cook 3-4 minutes or until just charred. Reduce the heat to medium. Add the tomatoes, 1/2 cup water, the chipotle peppers, chili powder, oregano, cumin, salt and pepper. Stir to combine and then simmer 15-20 minutes, or until the chicken is cooked through and shreds easily. Shred the chicken in the pot. Remove from the heat and stir in the cilantro. Preheat the oven to 450 degrees F. On a baking sheet, rub the tortillas with the remaining 1 tablespoon olive oil. Lay 4 tortillas flat and then layer evenly with cheese, rice, and chicken. Add the top tortilla. Transfer to the oven and cook for 5-8 minutes, then flip and cook another 5 minutes more, or until the cheese has melted and the tortillas are crisp. Meanwhile stir together the yogurt and lime zest. Season to taste with salt.Serve the quesadillas topped with diced mango, jalapeños, fresh cilantro, and drizzled with yogurt. EAT!
