Preheat oven to 400°. Place chicken between 2 sheets of heavy-duty plastic wrap, and flatten using a meat mallet or rolling pin. Place chiles and cheese evenly on top of chicken breasts. Roll up chicken, starting with short end; secure with wooden picks. Combine breadcrumbs and next 5 ingredients. Dip chicken rolls in melted butter; dredge in breadcrumb mixture. Place in a lightly greased 9 x 13 inch baking dish. Cover and chill 8 hours. Uncover and bake for 30 minutes or until chicken is done; discard wooden picks. Serve with salsa, if desired.
