Combine surimi seafood, spinach, cheese, herbs and garlic powder; mix well. Unroll crust from one can; pat into a 14x11-inch rectangle. Cut into 4 squares. Spoon 1/2 cup surimi mixture onto center of each square. Fold dough in half diagonally; press edges to seal well. Place on a lightly greased baking sheet. Repeat with remaining can and filling. Bake at 425 degree F for 8 to 10 minutes or until crust is browned.
