Dice 2-3 chicken breasts into 1” pieces and place in small bowl with enough marinade to cover the chicken. Marinate chicken breasts for at least 2 hours. Marinating overnight or longer is recommended for tastier results. Cut up 1 medium size onion, 1 green pepper and 1 tomato. In a large saute pan, add 2 tbsp olive oil and 1 tbsp butter. Add diced chicken and onion and cook for 3 minutes. Add green pepper and tomato and cook until chicken is cooked through and vegetables are tender. Add salt and pepper to taste. Serve with rice pilaf.
