Heat the oven to 350 degrees. Spray a 1-quart baking dish with cooking spray. In a 10-inch nonstick skillet, heat the butter over medium-high heat. Add the corn; cook for 5 minutes or until thoroughly thawed and heated, stirring occasionally. Reduce the heat to medium. Add the bell pepper, onion, garlic and jalapeno to the skillet. Cook for 3 to 4 minutes or until tender, stirring occasionally. Stir the flour into the sour cream; stir into the vegetable mixture. Cook for 1 minute, and then remove from the heat. Stir in all the remaining ingredients except ¼ cup of the Asiago cheese. Stir until the cheese is melted. Spoon into the baking dish; sprinkle with the remaining Asiago cheese. Bake for 20 minutes or until bubbly and thoroughly heated. Serve with your favorite crackers, crostini or baguette slices.
