01 - Combine chicken pieces with salt, pepper, lime juice, garlic, smoked paprika, cumin, and red pepper flakes in a bowl. Toss well to coat evenly. Cover and marinate for at least 15 minutes, up to 1 hour in the refrigerator for deeper flavor penetration.
02 - Heat olive oil in a large skillet or Dutch oven over medium-high heat. Add marinated chicken pieces and sear for 2-3 minutes per side until golden brown. Do not cook through completely. Remove chicken to a plate and set aside.
03 - In the same pan, add onion, bell peppers, and jalapeño. Sauté for 5-7 minutes, stirring occasionally, until vegetables soften and onions become translucent.
04 - Stir in diced tomatoes and tomato paste. Cook for 2-3 minutes until tomatoes begin to break down and release their juices, creating a thickened base.
05 - Return chicken and any accumulated juices to the pan. Pour in coconut milk, stirring well to combine with the vegetable mixture. Reduce heat to medium-low, cover, and simmer for 20 minutes until chicken is cooked through and sauce has slightly thickened.
06 - Taste the sauce and adjust seasoning with additional salt, pepper, or red pepper flakes as desired. Serve hot, generously topped with fresh chopped cilantro and accompanied by lime wedges. Pairs excellently with white rice or crusty bread.
