Rinse brown rice well. Place rice, water and salt into large pot. Cover, bring to boil, reduce to simmer and cook until rice is completely soft. Stir with a fork to fluff.
Cool for 30-45 minutes on the counter. Divide rice between freezer bags into 4 equal portions. Remove all the air, seal and freeze.
To reheat, open bags, add in 1-2 tablespoons of water and microwave 3-5 minutes or until hot. Serve as you like.
