    This recipe has major issues. First, the picture shows a layered dish yet the directions say to combine everything in the pan. Second, it calls for 2 cups of cheese but the directions actually account for 3 cups of cheese. Following the directions yields a tomato soup like dish with polenta floating in it. I am currently trying to add the rest of the tube of polenta to see if it’ll thicken but hopes aren’t high. Good thing I have some frozen pizzas to feed my family tonight.
