Season the chicken. Pat the chicken dry.
Toss with 1/2 teaspoon salt, 1/4 teaspoon pepper, smoked paprika, and cumin. This quick seasoning helps the chicken brown and adds flavor from the start.
Sear the chicken. Heat olive oil in a large, deep skillet or Dutch oven over medium-high. Add the chicken in a single layer and cook 3 to 4 minutes per side until lightly browned.
It doesn’t need to be fully cooked yet. Transfer to a plate.
Cook the aromatics. In the same pan, reduce heat to medium. Add the onion and bell pepper with a pinch of salt.
Cook 4 to 5 minutes until softened. Stir in the garlic and oregano, and cook 30 seconds until fragrant.
Toast the rice. Add the rice to the pan and stir to coat with the oil and veggies for 1 to 2 minutes. This step helps keep the grains fluffy and adds a nutty flavor.
Add broth and spices. Stir in the bay leaf and turmeric (if using).
Pour in chicken broth: 4 cups for brown rice or 3 cups for white jasmine/basmati. Scrape up any browned bits from the pan.
Simmer gently. Return the chicken (and any juices) to the pan. Bring to a gentle simmer, then reduce heat to low, cover, and cook until rice is tender. Brown rice: 35 to 45 minutes. White rice: 15 to 20 minutes.
Add peas and greens. In the last 5 minutes of cooking, stir in peas and spinach or kale if using.
Cover and let them steam until vibrant and tender.
Finish and rest. Remove from heat. Stir in lemon juice and half the herbs. Taste and adjust salt, pepper, or acid.
Cover and let rest 5 minutes so the rice settles.
Serve. Fluff with a fork, remove the bay leaf, and top with remaining herbs. Add a drizzle of olive oil or a sprinkle of red pepper flakes if you like a little heat.
