Preheat the oven to 375°.  Slice horizontally into the middle of the chicken breast, but do not slice all the way through.  This creates a pocket for the filling.

In a small bowl, combined the cream cheese, cheddar cheese, crumbled bacon, and jalapeños. 

In a bowl, combine the breadcrumbs and BBQ seasoning.

In another bowl, lightly beat the egg.

Divide the filling into 2 equal portions and stuff each chicken breast.  Dip the stuffed chicken breast in the egg, coating all sides.  Then dip into the breadcrumb mixture, coating all sides.  Repeat with the other chicken breast.

Place on a baking sheet lined with foil and bake at 375° for 30-35 minutes, until the chicken reaches an internal temp of 165°.
