Preheat your oven to 350 degrees F. Cut the tops off the jalapenos, then slice in half. Use a spoon to scoop out the sides and the vein. In a large mixing bowl, combine the pork sausage, cheeses, and Worcestershire sauce. Scoop a rounded tablespoon of the mixture into each jalapeno. Place on a baking sheet and bake for 30-35 minutes, or until the pork reaches 160 degrees F internally.
