Preheat oven to 300 F and place wire rack on top of aluminum foil-lined baking sheet.

In medium bowl, mix softened cream cheese, Parmesan cheese and 1 teaspoon Cajun seasoning.

Smear cream cheese into jalapeno halves. Top each with one shrimp, tail up. Wrap with one piece of bacon and secure with toothpick.

Place jalapenos on wire rack and bake 35 minutes, or until shrimp and bacon are cooked through.
