Very rich! Salty too! Between the feta cheese & parmesan cheese. Next time I would just top it with a touch of parm. and omit it inside. I used fresh spinach that I cooked with the mushrooms. When I added the flour is when I added the dry milk and left out the water using the spinach juice in it`s place. The feta cheese I used was herbed. I butter can be cut back I had 1/2 a cup left over. I wasn't sure about making slits as you see in the picture I cut all the way through before baking which made it easy to slice at serving time. After 45 minutes baking I turned the oven down to 345 degrees. Didn't want it to brown any more then as you see it! This is an easy recipe to assemble I had a fun time making it. And a good time eating it.
