Heat oven to 375° F. Brown ground beef in 10-inch nonstick skillet; drain grease. Reduce heat to medium-low. Stir in salsa, corn, cumin and salt. Cook 3 to 5 minutes until corn is tender.

Unroll crescent roll dough separating into 4 rectangles. Place on ungreased cookie sheet. Press each piece of dough into an 8x4-inch rectangle; sealing the center seam.

Spoon ½ cup beef mixture onto one end of each rectangle to within ½-inch of edges. Top with shredded Mexican 4 cheese. Carefully fold dough over filling (calzone will be full) pressing seams to seal tightly. Lightly prick top of each calzone with a fork to allow steam to escape.

Bake 15 to 20 minutes or until deep golden brown. Remove from cookie sheet
