Sear the Chicken: Fry the chicken in a pan until it is nearly done.
Sauté Aromatics: Add the chopped onion, garlic, and chopped tomato to the pan with the chicken. Sauté for a few more minutes.
Toast Rice: Add the rice to the pan and fry it for about 1 minute to coat it in the juices.
Simmer: Stir in the pepper, crushed paprika, chicken broth, water, and Knorr cube. Cover the pan and cook over low heat.
Finish & Serve: Once the liquid is absorbed and the rice is tender, stir in sliced Spanish olives and serve with a dollop of sour cream.
