Add the tomatoes, shrimp, fish and bay leaves, stir.
Add the rice, stir gently and add the water.
Continue to stir while bringing to a boil, then reduce the heat, cover and simmer for about 15 minutes or until the rice has absorbed most of the liquid.
Turn off the heat, then fold in the oysters, cover and let sit for about 8 minutes, during which time the jambalaya will continue cooking the residual heat.
To serve, transfer to a serving bowl and mix in the green onions. Season with hot sauce.
