In a large saute pan, over medium heat, add the oil. When the oil is hot, add the Tasso and saute for 2 to 3 minutes. Add the corn, onions and bell peppers. Season with salt and cayenne pepper. Saute for about 10 minutes. Add the tomatoes and simmer, stirring occasionally, for 15 to 18 minutes, or until the corn is tender. Add the cream, stir, and remove from the heat.
