Cook about two large boneless chicken breasts in the oven with lemon pepper seasoning or you can cook chicken whatever way you like. Cut chicken in strips or bite size pieces.
Mix soup,cheese, mayo,sour cream, lemon juice in a bowl and add cooked chicken and artichokes. Put cooked noodles in a buttered casserole and top with chicken and soup mixture. Stir to incorporate and add capers.
Bake at 350 degrees for about 25 minutes, long enough to melt cheese.
