Step 1

Spray baking sheet with no-stick cooking spray. Place rolls onto sheet; cover lightly with plastic food wrap. Let rise at room temperature 1 1/2-2 hours or until completely thawed and rolls feel soft.

Step 2

Divide cheese cubes evenly among centers of rolls. Seal dough around cheese, pinching edges tightly. Place onto baking sheet; let rest 15 minutes.

Step 3

Heat oven to 425°F. Line another baking sheet with parchment paper; set aside.

Step 4

Place water into large saucepan; bring to boil over high heat. Carefully add baking soda and sugar. (Water will bubble up, then return to a gentle boil.) Drop 4 rolls into gently boiling water; cook, turning once, about 30 seconds per side or until surface of dough has lightly bubbled appearance. Remove with slotted spoon; place onto parchment-lined baking sheet. Repeat with remaining rolls.

Step 5

Brush each roll with beaten egg; sprinkle with coarse salt. Bake 14-16 minutes or until golden brown. Cool 3 minutes. Serve warm.
