Preheat your oven to 375°F and line a large baking sheet with parchment paper.
Brown the sausage in a skillet over medium heat, breaking it into small crumbles (about 8-10 minutes). Transfer to paper towels to drain, then cool completely.
In a mixing bowl, combine the cooled sausage with both grated cheeses and optional seasonings if using.
Place an inverted 5-6 inch bowl in the center of your prepared baking sheet. Separate crescent dough into triangles and arrange them in a circle around the bowl, with wide ends overlapping at the bowl's edge and points extending outward.
Carefully remove the bowl. Distribute the sausage-cheese mixture evenly around the ring on the wide portions of dough.
Fold each dough triangle point over the filling and tuck underneath the inner edge of dough to secure.
Whisk together egg and water, then brush generously over the entire dough surface.
Bake for 20-22 minutes until deeply golden, rotating pan halfway through baking.
Allow to cool 5-7 minutes before transferring to a serving platter.
Garnish with fresh parsley and serve with dipping sauces of choice.
