Chicken Broccoli Crescent Ring

The other day I made this for some friends and it was really yummy (and pretty!). I used this recipe but altered it a bit based on what I had on hand and my tastes, so here's my version:

2 cups cooked chicken (I cooked it on the stove in olive oil, salt, pepper and some Italian seasoning)
1 cup raw broccoli, chopped
1 T chopped garlic
1 cup cheddar or cheese of your choice, grated
1/2 cup mayo
1 t dill weed (this is approximate--I'm not really sure how much I used)
1-2 T Dijon mustard
Salt and pepper
2 packages refrigerated crescent rolls
1 egg white

1. Preheat the oven to 375 F.
2. Line a pizza pan with foil and spray with cooking spray.
3. Put all the ingredients (except only half of the cheese) but the crescent rolls into a mixing bowl and stir together.
4. Separate the crescent rolls and arrange overlapping the large sides of the triangle on the pizza pan.
5. Spoon the filling in a circle over the dough that is overlapped and then fold the short end of the triangles to the center. Tuck the ends underneath.
6. Brush an egg white onto the top of the crescent dough.
7. Bake for about 20 minutes.
8. Sprinkle remaining cheese on top.
9. Bake for about 10 more minutes.

I'm anxious to try out some variations on this recipe (like with an Italian filling), but I'd like to use dough that doesn't have trans fat like this crescent dough does.
