Combine the flour, cornmeal and 1 tablespoon of the Vegetable Magic in a small bowl.
Sprinkle the tomato slices evenly with a total of 2 teaspoons Vegetable Magic and pat it in well.
Fry the bacon in a 12-inch skillet over high heat, stirring occasionally, for 3 minutes. Reduce the heat to medium and cook until the bacon is browned and crisp, about 4 to 5 minutes. Remove the bacon with a slotted spoon, drain and set aside. Pour off the fat from the pan, reserving ¼ cup.
Heat the reserved bacon drippings and the vegetable oil in the same skillet over high heat for 5 minutes. While the oil mixture is heating, dredge the seasoned tomato slices in the flour/cornmeal mixture, one at a time, and reserve the leftover flour mixture. When the oil mixture is hot, add 6 of the tomato slices, or as many as will fit in a single layer, and fry, turning twice, until browned, about 10 minutes. If the tomatoes brown too quickly, reduce the heat slightly. Remove with a slotted spatula and drain on paper towels. Fry the remaining tomato slices and drain them. Do not drain the oil mixture from the skillet. Chop 2 of the fried tomato slices and set aside.
Add 3 tablespoons of the reserved seasoned flour mixture to the oil in the skillet and cook, whisking constantly, for 3 minutes. Add the chopped tomatoes, stock and cooked bacon, and cook, whisking, for 2 minutes. Add 1 cup of the cream and the remaining Vegetable Magic and cook, whisking, for 3 minutes. Whisk in the remaining ½ cup cream and remove from the heat. To serve, toast the muffin halves. Place a tomato slice on each half and cover with ¼ cup of the gravy.
