Dice the chicken breast into 1-inch pieces and season evenly with the sea salt and black pepper.
Heat the olive oil in a large non-stick skillet over medium-high heat and brown the chicken pieces for 4-5 minutes until golden.
Add the diced yellow onion and red bell pepper to the skillet and sauté for 3 minutes until the vegetables begin to soften.
Stir in the minced garlic and jasmine rice, toasting the grains for 1 minute until they become fragrant and slightly translucent.
Pour in the tomato puree, chicken broth, and dried oregano, stirring well to ensure the rice is submerged and the chicken is evenly distributed.
Bring the mixture to a gentle boil, then reduce the heat to low, cover the skillet with a tight-fitting lid, and simmer for 15-18 minutes.
Remove the skillet from the heat and let it sit covered for 5 minutes to allow the steam to finish cooking the rice before fluffing with a fork and serving.
