1 1/4 pounds boneless, skinless chicken breasts, cut into 2-inch chunks
1/4 cup all-purpose flour
2 tablespoons vegetable oil
1 medium onion, finely chopped
2 cloves garlic, finely chopped
4 ounces cooked chorizo sausage, cut into 1/4-inch-thick rounds
1 1/2 cups long-grain rice
3 1/2 cups low-sodium chicken broth
1 15-oz. can diced tomatoes, drained
1 cup frozen peas
Sprinkle chicken with salt and dredge in flour. Warm 1 Tbsp. oil in a large, deep nonstick skillet over medium-high heat. Cook chicken until browned on all sides, about 6 minutes total. Transfer to a plate.
Heat remaining oil in skillet and add onion and garlic. Cook, stirring, until softened, about 3 minutes. Add chorizo and cook until lightly browned, about 2 minutes. Stir in rice, broth, tomatoes and 1/2 tsp. salt. Bring to a boil, add chicken, cover, reduce heat to low and cook until rice is tender and chicken is cooked through, 10 to 12 minutes.
Remove from heat, stir in peas, cover and let stand until peas are heated through, about 5 minutes.
