I was skeptical about the sauce, but it absolutely works. I found 2 servings to be about right per meal. I wanted another helping after the first taste!
If you keep to the recipe with a chicken layer on top, I suggest keeping it in the oven until the sauce starts to brown slightly, guaranteeing the rest of the dish has solidified enough for easy serving. Bonus Tip: When following the link to the recipe, the beginning is rhetoric. A clean list of ingredients and instructions is at the very bottom of the page.
