Place the Dutch oven back on the stove, over medium high heat.
Add olive oil to the pot and sauté onions, carrots, and garlic for a few minutes to soften them up.
Add rice to the pot and increase the heat to high. Cook while periodically stirring for ten minutes, allowing the rice to get a bit of color and crisp.
Add three cups of the braising liquid into the pot (supplement with chicken stock if there is less than three total cups), pureed fire roasted tomatoes, red chili pepper flakes, and salt.
Bring to a boil, then lower the heat to low and cover for fifteen minutes.
Quickly remove the lid and throw in your frozen peas, then put the lid back on.
Turn off the heat and let steam for five more minutes.
After five minutes, fluff the rice with a fork then add your chicken thighs and whatever juices they left behind onto the top of the rice and cover.
Let sit for another ten minutes then serve. Taste for salt and spice, now is the time to make it perfect!
Optional: Garnish with thinly sliced jalapeno, lime, and cilantro.
