Season the chicken: In a small bowl, combine the cumin, paprika, chili powder, onion powder, garlic powder, salt, and black pepper. Rub this spice mixture all over the chicken thighs, making sure both sides are well coated.
Sear the chicken: Heat the olive oil in a large pan over medium-high heat. Add the chicken and sear until golden brown on both sides, about 4–5 minutes per side. Once seared, remove the chicken from the pan and set it aside.
Prepare the rice base: In the same pan, add the sofrito, Sazón, chicken bouillon, and tomato sauce. Stir to combine, scraping up any browned bits from the bottom of the pan for extra flavor. Add the rice and stir until every grain is coated in the sauce. Pour in the water and add the green peas. Taste and adjust the seasoning with salt if needed.
Cook everything together: Place the seared chicken on top of the rice. Bring the mixture to a gentle boil and cook uncovered for 5 minutes. Then reduce the heat to low, cover the pan with a lid, and let it simmer for 30 minutes, or until the rice has absorbed the liquid and the chicken is fully cooked.
Rest and serve: Remove the pan from the heat and let it rest, covered, for 5–10 minutes. Serve the chicken and rice topped with fresh chopped cilantro, creamy avocado slices, and a squeeze of lime.
