Heat oven to 375°F.
If using crescent rolls: Unroll both cans of dough; separate into 8 (4x7 1/2 inch) rectangles. Firmly press perforations to seal. If using dough sheets: Unroll both cans of dough, cut each rectangle into 4 rectangles, for a total of 8 (4x7 1/2-inch) rectangles.
For each sandwich, place 1 rectangle of dough on ungreased cookie sheet. Top with 1 slice of ham. Place cheese at one end of ham slice. Place 2 chicken patties on cheese. Fold 2/3 of dough over chicken, leaving about 1 1/2 inches of chicken uncovered. Press sides of sandwich with fork to seal edges.
Bake 15 to 17 minutes or until crust is golden brown and chicken is hot.
