Chicken Calzones

I can't believe I haven't posted this recipe yet. It is one i used to make all the time. I brought out the recipe again for gourmet girls (an enrichment group) last week. It's pretty healthy if you follow the recipe.

1 pkg regular active dry yeast
1 c. warm water
1 Tbsp. sugar
2 tsp. vegetable oil
1/2 tsp salt
1 1/2 c. all-purpose flor
1 1/4 - 1 3/4 c. whole wheat flour
1 egg white beaten

Chicken -mushroom filling
1 c. cut up cooked chicken
4 oz chopped mushrooms
3/4 c. shredded mozzarella cheese
1/4 c. chopped onion
8 oz pizza sauce.
2 Tbsp. Parmesan cheese

Dissolve yeast in warm water in a large bowl. Stir in sugar, oil, salt and all-purpose flour. Beat until smooth. Mix enough whole-wheat flour to make dough easy to handle. Turn dough onto lightly floured surface; gently roll in flour to coat. Knead about 5 minutes or until smooth and elastic. Cover and let rest for 5 minutes.
Heat oven to 375 degrees F. Prepare chicken mushroom filling: mix all ingredients. Reserve.
Spray large cookie sheet with non-stick cooking spray. Divide dough into 6 equal parts (I usually do 8). Roll or pat into 7 -inch circle on a lightly floured surface, turning occasionally to coat with flour. Place about 1/3 c. of filling on half of each circle; spred to within 1 inch of edge. Fold dough over filling; press edge with fork to seal (or twist, or pinch etc.) Place on cookie sheet; brush with egg white. Cut several slits in top to vent steam. Bake 25-30 minutes or until golden brown.
