Preheat grill for low setting. Put on a pair of latex or kitchen gloves before preparing jalapenos. Slice each jalapeno in half lengthwise and remove seeds and veins with spoon. Set aside. Combine filling ingredients in a medium bowl. Spoon roughly 2 tablespoons on mixture into jalapeno halves. Place peppers onto grill and cook for 6-8 minutes, or until bottoms of jalapeno begin to char. Remove from grill and serve.
