This is pretty self explanatory. Once you have all the ingredients together and ready the dish just has to be assembled and baked in a 350 degree oven for about 45 minutes or so. All of these ingredients are interchangeable, zucchini can be used instead of spinach. the potatoes can be substituted with thick tomato slices. The was great as it is. This is layered with spinach on the bottom of the dish, chicken breast or thighs on top of that. Next pre-sauteed onions and sweet pepper and then the stewed tomatoes and mushrooms. Finally a layer of potatoes and some stock and it is ready to be baked. Very important to season as you go because once the dish is finished you can't season it until it is on the plate. I used a lot of garlic in each stage of cooking here.
For the last five minutes or so the oven should be put on ' broil ' and the potatoes can be brushed with a little melted butter to help the color.
