This is one of those recipes my mom used to make when she was working full-time that tasted as though it was made and slaved over for hours...
1 2/3 C frozen mixed veggies - thawed and drained (frozen don't get quite as mushy when the pie is done)
1 C cooked chicken, cut or shredded
1 can Cream of Chicken Soup
1 C Bisquick (or other baking mix - I make my own)
1/2 C milk
Heat oven to 400 (425 for high altitude). Mix veggies, chicken & soup in 9" pie plate. Stir baking mix, egg and milk together and pour over chicken mixture. Bake for 30 minutes.
Once this is made, it can be frozen, and then just defrosted and re-heated in the oven.
