Impossibly Easy Ham Swiss Pie

Posted by request; i've not tried this. Would be a quick weeknight meal; i also think it'd be good to add mushrooms. From a bisquick cookbook.

Heat oven to 400.

Grease 9-inch pie plate.

Sprinkle ham , cheese& onions onto pie plate.

Stir remaining ingredients until blended.

Pour into pie plate over ham / cheese.

Bake 35-40 minutes or until knife inserted into pie comes out clean.
