Heat a frying pan to medium; add vegetable oil, chicken, onion and seasoning. Cook until onions are soft and chicken lightly browned.
Add Red Bell Pepper and tomato paste. Stir well and cook for approximately 2 minutes. Pour in cold water and add brown rice. Stir well and bring to a boil.
Reduce heat to low; cover and gently simmer for 20 - 30 minutes, or until rice is tender and chicken is fully cooked. Season with Sea Salt and Pepper.
