Heat 2 Tbsp. of olive oil in a large pot on medium heat. Add rice and stir until it starts to crackle (about 2 minutes). Add water and 1/2 tsp. of salt. Cover pot and bring to a boil, then reduce heat and allow to cook for about 30 minutes, until rice is soft. In a deep skillet, add 1 Tbsp. of olive oil and preheat over high heat. Cook chicken in skillet until no longer pink (about 4 minutes). Reduce heat and add all other ingredients. Bring to a boil, then reduce to a simmer and cover for 10 minutes. Serve over the cooked brown rice.
