Butter outside of bread slices and sprinkle with Italian seasoning. Place one slice of bread, butter-side down in a pan over medium heat. Layer cheese, tomato, season tomato with salt and pepper, basil, and another slice of cheese. Place remaining bread slice on top butter-side up. Cook until bread is toasted and cheese is melted, flipping once. About 2-3 minutes per side. Slice and serve with tomato soup and Caesar salad.
