Start water boiling. While it comes to a boil, prepare the jalapeno peppers by cutting off stem end and scooping out the insides and seeds.
Place peppers in steamer basket. Cover and steam over boiling water for 15 minutes. Rinse under cool water; drain. Set aside.
Cut each of the cheese sticks in half. Tuck each one inside a boiled pepper. (You may have to trim them further to make sure they fit inside peppers.)
Wrap a slice of ham around each end of a pepper.
Unroll the sheet of crescent roll dough and separate into triangles. Place the wrapped pepper at the pointy side of the triangle and roll up. Place on ungreased baking sheet. Bake 11-13 minutes or until golden brown.
