Not many ingredients but fresh is the key! Your kids shouldn't even mind eating spinach or mushrooms after tasting this. I have been making this dish for years and now don't really even need to measure ingredients. I just make to taste and we usually have this as a side dish for red meat. Pick your favorite mushroom. I like to use cremini. I have used portobello before but the gills make this dish an ugly brown color, so if you use portobello, remove the gills. The original recipe calls for boiling the spinach for one minute before sauteing but I skip that step now and just throw the bag of baby spinach in the saute pan and it wilts in the pan. It's your choice. Also, be gentle with the salt and pepper because too much ruins the dish. It's best to use a little then add more if needed after tasting, but most times you won't want to ruin the flavor.
