Adjust oven rack to middle position and heat
oven to 350 degrees. Process cilantro, 1/2 cup onion, Cubanelle, garlic, and
cumin in food processor until finely chopped, about 20 seconds, scraping down
bowl as needed. Transfer mixture to a bowl. Pat chicken dry with paper towels and
season well with salt and pepper. Heat oil in Dutch oven over medium heat until
shimmering. Add chicken to pot skin side down and cook without moving it until
skin is crispy and golden, 7 to 9 minutes. Flip chicken and continue to cook
until golden on second side, 7 to 9 minutes longer. Transfer chicken to plate. Pour
off all but 2 tablespoons fat from pot and heat over medium heat until
shimmering. Add remaining 1/2 cup onion and cook until softened, 3 to 5
minutes. Stir in rice, coriander, and achiote powder and cook until edges of rice turn translucent. Stir
in broth, olives, capers, bay leaves, chopped aromatics, lemon juice, 1
teaspoon salt, and 1/2 teaspoon pepper, scraping up any browned bits. Nestle
chicken into pot along with any accumulated juices and bring to vigorous simmer.
Cover, transfer to oven, and bake for 20 minutes. Transfer pot to wire rack and
let stand, covered, for 15 minutes. Discard bay leaves, fluff rice with fork
and stir in peas. Serves 4 to 6.
