01 - Combine cilantro leaves, jalapeños, garlic cloves, mayonnaise, sour cream, cotija cheese, lime juice, olive oil, salt, and pepper in a blender. Blend until completely smooth and creamy. Transfer to a container and refrigerate until ready to serve.
02 - Pat chicken pieces dry with paper towels. Season generously on both sides with salt, black pepper, and ground cumin, rubbing the spices into the meat.
03 - Heat olive oil in a large skillet or Dutch oven over medium-high heat until shimmering. Add seasoned chicken and sear for 3–4 minutes per side until deep golden brown. Remove chicken from pan and set aside on a plate.
04 - In the same pan, add chopped onion, minced garlic, and diced red bell pepper. Sauté, stirring occasionally, until vegetables are softened and fragrant, about 4 minutes.
05 - Add rice to the pan and stir constantly for 1–2 minutes to coat grains with the aromatic oils and lightly toast. Meanwhile, blend fresh cilantro with ½ cup chicken broth until smooth. Pour the green cilantro mixture over the rice and stir well to combine.
06 - Return seared chicken to the pot. Pour in remaining chicken broth and bring to a boil. Immediately reduce heat to low, cover tightly with a lid, and simmer for 20 minutes.
07 - Remove lid and scatter frozen green peas over the rice. Stir gently to distribute without breaking up the chicken. Cover again and cook for 5–7 more minutes until rice is tender, liquid is absorbed, and chicken reaches internal temperature of 165°F.
08 - Remove from heat and let stand covered for 5 minutes. Fluff rice gently with a fork, being careful not to shred the chicken. Serve hot with generous spoonfuls of chilled green sauce drizzled over the top and fresh lime wedges on the side.
