Heat 1 tablespoon extra virgin olive oil in a large skillet (that can be fitted with a lid).
Season 1 pound boneless skinless chicken breasts (cubed) with 1 teaspoon kosher salt and 1 teaspoon black pepper. Add the seasoned chicken to the heated oil in the skillet and brown the chicken, for about 2 minutes per side, or until browned.
Once the chicken has browned, add ¼ cup dry white wine to the pan and scrape up all the browned bits on the bottom of the pan.
Add 1 tablespoon minced garlic and 1 cup grape tomatoes (halved) and saute for 1 minute to toast the garlic.
Add 2 cups low sodium chicken stock, 1 tablespoon fresh thyme leaves, and 1 cup minute brown rice, stirring to incorporate. Bring the mixture to a boil, cover, and reduce heat to a low simmer. Simmer for 10 minutes, or until the liquid has been absorbed and the rice is tender.
Turn off the heat and let the skillet set for 10 minutes. Remove the lid and stir in 6 ounces spinach and ½ cup crumbled feta cheese. Drizzle with additional olive oil if desired and serve.
