Prepare brown rice according to package directions.
On a separate plastic cutting board, trim the excess fat from the chicken thighs and dice into 1 inch cubes.
Place a skillet on medium heat and add the oil. Once the pan is hot, add the chicken cubes and cook until they are browned on all sides, about 3-4 minutes.
Add the water, lime juice, thyme, onions, peppers, garlic, salt and pepper. Cook for another 3 minutes.
Reduce heat to low, cover, and cook for 15-20 minutes.
Serve over brown rice.
