Cresent Apple Dumplings

1 tube refrig. crescent rolls
1 med. granny smith or I like Jonagold, pared, cored and cut in to 8 wedges
1/2 C. sugar
1/4 C butter, melted
1 tsp. vanilla extract
6 Tbsp. grapefruit or citrus flavored soda
1-2 tsp apple pie spice

Unroll and separate the crescent rolls into 8 triangles
Place an apple wedge in the large end of the triangle and fold the edges up over it, pinching to seal.

In a bowl combine the sugar, melted butter and vanilla. Spoon this over the dumplings. Slowly pour the soda around the dumplings. Sprinkle with Apple Pie spice
Bake @ 350F for 25-30 minutes
