In a large skillet over medium-high heat, add oil and when hot, add chicken – work in batches if needed. Cook until brown on both sides, about 6 to 8 minutes.
Transfer to a plate while working with the remaining ones; set aside. Keep about 2 tbsp. fat in skillet and discard the rest.
Reduce the heat to medium and add onions, red peppers and jalapeño peppers. Sauté for 3 minutes, scraping the bottom of the skillet to dislodge any brown bits.
Add garlic and sauté for 1 minute. Add tomato paste and stir to coat.
Add raw sugar, cumin, oregano leaves, turmeric, sea salt, and pepper; stir well.
Add rice and stir constantly until fragrant and has absorbed all the fat from skillet, about 2 minutes.
Add chicken broth, stir, increase heat and bring to a boil.
Stir in peas and return chicken thighs including any accumulated juices.
Cover, reduce heat to medium-low and cook for 20 to 25 minutes or until the liquid is absorbed.
Sprinkle on chopped cilantro and serve immediately.
