If you are on a diet, skip this dish! If you would like an authentic creamy chicken dish that is served on puff pastry and is out of this world, then please try this old family recipe. You will be happy you did!
Remove puff pastry from the freezer and let semi thaw (10 minutes).
Unfold pastry sheet, lay it flat and cut into 2 inch squares. Place squares onto a lightly greased baking/cookie sheet. Bake at 400 degrees for 10 minutes or until slightly browned on top. Set aside and keep warm.
Saute mushrooms in butter until softened. Add cooked chicken, pimento and 1/2 can of chicken stock/broth. Mix flour with remaining stock/broth and mix well until there are no lumps. Slowly add flour/stock mixture to the chicken/mushroom/pimento mixture. Cook over medium heat and stir frequently until thickened.
Once mixture is thickened, slowly add milk and stir until thoroughly blended and slightly thickened but do not boil!
