i have a king kooker jalapeno "stand" which is so awesome - you can get 36 cored jalapenos in it & i just use it in the oven. Coring the peppers is easier than you think, esp if you get those huge jalapenos during the summer. I use the same kind of recipe as you - cream cheese + some shredded cheddar, topped w/ bacon. Probably be good w/ sausage too.
yes the stand is a uni-tasker but it does its one little task very well.
maybe i'll make some this weekend, they're nice to eat while you're bbq-ing.
