Combine cream cheese and cheddar cheese in a bowl. If you want really hot poppers, roll the peppers between your hands before taking the seeds out, this will bring the hot out of the seeds. But this is only if you like REALLY hot poppers! Take the seeds out of the peppers and slice down one side of pepper. Stuff the peppers with the cheese mixture. Beat eggs and then dip stuffed peppers in egg. Coat pepper in breadcrumbs. Gently place popper in heated vegetable oil until breadcrumbs are lightly browned.
