Easy Chicken Pot Pie

I got this recipe from my friend Amy Kartchner.  It is really easy and super delicious.  The only modification I have had to make in France is to use fresh chicken cooked for about 2-3 hours in a crock pot rather than Costco canned chicken.  (I can't find any canned chicken of any kind here.)  Then I have to increase the salt amount by a little and cut the chicken up finely.  It's a little more work, but it's still really good, although believe it or not, I still prefer canned chicken in this recipe for both the taste and ease of preparation.

Ingredients:
1/3 C. butter
1/3 C. flour
1/3 C. onion, diced
1/2 t. salt
1/4 t. pepper
1-3/4 C. chicken broth (1 can)
2/3 C. milk, the creamier the better
1 bag frozen peas and carrots
2 12.5-oz. cans chicken, drained
2 premade pie crusts

Directions:
Preheat oven to 425 F.  In a large skillet or saucepan, melt the butter and add the flour and onions.  When onions are translucent, add the salt and pepper, chicken broth, and milk over low heat.  Simmer until it thickens.  Add the peas and carrots and the chicken.  Mix well.  Spoon into a pie plate with one pie crust already on it.  Spread another crust on top.  Pinch and flute edges.  Cut 4 slits on top to vent.  Bake for 40-45 minutes.  Use foil around edges of cust to prevent overbrowning.  Delicious! Even kids like this.
