Heat a medium skillet over medium heat, then add sausage. Cook until sausage is cooked through and browned, about 10 minutes. Drain sausage, then pour crumbled sausage onto paper towel-lined plate to soak up excess oil.
Cut off the tops of all jalapenos, then slice each down the middle, lengthwise. Remove seeds and veins.
In a medium bowl, mix cream cheese and parmesan. Once sausage has cooled down, mix with cheeses.
Spoon mixture into jalapeno shells, then line them side by side on a baking sheet. Bake peppers for 20-25 minutes, until tops have browned. Let cool about five minutes before serving.
