Cook the rice (check the recipe). While the rice is cooking, prepare the remaining ingredients.

Place the olive oil, oregano, and pepper (about ⅓ to ½ teaspoon each) in a bowl and mix together. Clean the chicken breast and cut it into smaller pieces. Put the chicken pieces into the bowl with the prepared marinade and coat them thoroughly.

Heat the pan. After a moment, add the meat. Fry for a while, stirring constantly.

Once the meat loses its raw color, reduce the heat and add the tomato passata. Simmer until the sauce thickens and the meat is cooked through, about 7-10 minutes. If necessary, add a little water while simmering, but be careful not to use too much.

Then add the rice and season with salt to taste. Mix thoroughly.

Transfer to a plate.
