Flatten chicken to ¼" thickness. In a small bowl combine cheese,
chilies & onion. Spread ¼ of cheese mixture on each chicken breast.
Roll and secure with toothpicks. Dip chicken in melted butter & then
Place in a greased baking dish. Cover and bake @ 375F for 50 minutes.
Uncover for 10 more minutes to brown.
NOTE: You can substitute a beaten egg for the melted butter. You
can add seasonings to the egg/butter instead of the crumbs. I use
seasoning salt & pepper but you can use whatever seasonings you prefer.
