Lay 24 frozen dinner rolls on a piece of parchment paper that has been very lightly sprayed with non stick spray. Put a piece of plastic wrap over the top that has been lightly sprayed with non stick spray so they don't dry out.
Allow them to defrost and rise a bit for 3 hours. Put a bit of olive oil on your hands and roll 2 pieces out into long snake shapes. Pinch together at one end.
Braid the two strips of dough and then make into a circle. Pinch two ends together to create a sort of circle or wreath. Place on a baking sheet with a new piece of parchment underneath.
Whisk together egg white and water, use a pastry brush to coat top to make shiny. Sprinkle sprinkles on top if desired.
Preheat oven to 350 degrees F, bake for 17 minutes until very lightly browned on top and cooked thru in middle. Remove and slide paper off so rolls don't continue to bake.
