This one-pot chicken dinner, inspired by the traditional dish of Spain and Latin America, comes together easily in the slow cooker.
Combine bell peppers, onion, garlic, tomato sauce, diced tomatoes, broth, chili powder, paprika, 1/2 teaspoon salt, pepper, cumin, and saffron (or turmeric) in a 6-qt. slow cooker. Nestle chicken into the mixture until submerged. Cover and cook on Low for 5 1/2 hours.
Stir in rice, peas, and the remaining 1/2 teaspoon salt. Cover and cook until the rice is tender and most of the liquid is absorbed, about 30 minutes more.
Using 2 forks, shred the chicken in the slow cooker. Top each serving with 1 tablespoon olives and garnish with cilantro, if desired.
