Preheat oven to 400.
Unroll puff pastry onto the counter or a cutting board.
Sprinkle with a little all-purpose flour and roll out the dough to an even layer, spreading to make a larger rectangle.
Fold over the pastry dough or cut it in half to make two equally-sized rectangles.
Set aside one rectangle to place on top later.
Flip the dough so that the floured side is down and lay it on your cooking surface, such as a baking stone, cookie sheet, or oven-safe pan.
Evently spread the cream cheese on the rectangle.
Evenly top with a layer of sliced ham.
Repeat with sliced cheese.
Top with the second dough piece.
Using a drinking glass with about a 4-inch diameter, press it down in the middle of the rectangle.
Use a knife to cut the “rays” of the sun. First, make four cuts to create quadrants, then cut those in half and each of those in half. You should have 16 equally portioned pieces.
Lift the “ray” closest to you, all the layers.
Hold it between your fingers and twist it, making two full turns. Lift it to the middle and twist it to the end, pressing the end down on your cooking surface.
Repeat this with the other “rays,” making sure to twist them all in the same direction.
Brush an egg wash over the middle and all the twisted pieces, trying to coat all the pastry dough where possible.
Place the Sunbraid in the oven on a middle rack, with room for the pastry to rise.
Bake for 12 minutes and check until fully cooked. May take up to 20 minutes to cook where there is an even cook and golden brown finish to the pastry.
Remove from oven and serve warm.
Serve on a spring buffet or with dips, crudites, and crackers on the side.
