Preheat oven to 400 degrees F. Line a baking sheet with aluminum foil.
Mix cream cheese, mozzarella cheese, and Cajun seasoning in a small bowl until evenly blended. Fill each jalapeno half with the cream cheese mixture and wrap with bacon. Make sure the bacon gets wrapped over the ends. Secure bacon with toothpicks and place onto the baking sheet.
Bake in the preheated oven until the bacon is done to your liking, about 20 minutes.
Myself and several friends of mine from work had a Mexican food party a few weeks ago, and I brought this recipe to the table. I added half an avocado to the filling mixture. The poppers didn't last long
