Melt butter with olive oil in a large, deep skillet over medium-high heat. Increase heat to high, and add shrimp and ham; cook, stirring constantly, 3 to 5 minutes or until shrimp turn pink. Reduce heat to medium high, add vermouth and next 3 ingredients; bring to a boil. Pour into a large, deep serving platter or individual bowls. Sprinkle with parsley, and serve immediately.
