Add the chicken, salsa agrodolce and olives. Season with salt to taste. Reduce the heat to low. Simmer, stirring occasionally, for 15 minutes or until the chicken is cooked through and the sauce is reduced.
Cook the rice in a medium-sized saucepan with boiling, salted water, referring to the cooking time specified in the rice packet instructions. Drain the rice.
