Heat oven to 375°F. Lightly grease large cookie sheet with shortening, or spray with cooking spray. Unroll 1 can of dough on work surface.
In small bowl, mix cheese and onions. Spread cheese and onion mixture evenly over dough. Unroll second can of dough; place on top of filling; press firmly. Cut into 8 (13-inch) strips. Twist each strip 4 or 5 times; bring ends together to form ring, and pinch to seal. Place on cookie sheet.
In another small bowl, beat egg and water until well blended; brush over dough. Sprinkle with sesame seed and garlic salt blend.
Bake 15 to 20 minutes or until golden brown. Immediately remove from cookie sheet; cool 5 minutes. Serve warm.
