Cheesy Mushroom Rounds

1 tube refrigerated crescent rolls
3/4 pkg. cream cheese, softened
1 can mushrooms, drained and chopped
2 Tbl. fresh grated parmesan cheese
2 tsp. poppy seeds
1 egg
1 Tbl. water
Additional poppy seeds for sprinkling

Unroll crescent dough into 2 long rectangles; place next to each other and seal seams and perforations.  Combine cream cheese, parmesan, poppy seeds and chopped mushrooms, mixing well. Spread over dough.  Roll jelly-roll style, starting on long edge, and seal edges. Slice with floss (like cinnamon rolls) about 3/4" thick.  Place on a baking sheet, lined with parchment or stone baking pan. Whisk together egg and water.  Brush on top of each round.  Sprinkle with a little additional poppy seeds.  Bake at 375 degrees until golden, about 12-16 minutes.
