Preheat your oven to 350°F.
On a round pizza stone or baking sheet, arrange the crescent roll triangles in a circular pattern, with the wide ends overlapping in the center to form a ring.
Spread a thin layer of Dijon mustard over the dough, followed by a drizzle of honey.
Layer the ham and Swiss cheese evenly around the ring.
Fold the narrow ends of the crescent rolls over the filling, tucking them under the center to create a complete ring.
Brush the top with egg wash and bake for 18-22 minutes, or until golden brown and the cheese is melted.
Remove from the oven and let it rest for about 3 minutes.
Brush with melted butter and sprinkle with poppy seeds if desired.
