The following morning, heat 8 cups water to a boil. Pour over the rice mixture in deep baking pan. In a food processor, pour 1/2 of the #10 can on tomatoes and chop until finely diced. Add to rice mixture and repeat with remaining tomatoes. Stir well. Cover tightly with aluminum foil and place into a preheated 350 degree convection oven. Bake for 50-60 minutes, until rice is tender and water is absorbed. Remove to steam table and serve hot.
