SPINACH: Frozen spinach is used because so much spinach is required. A bag of frozen spinach contains a mountain of fresh leaves. If you would prefer to use fresh spinach then you can but just factor in the extra time needed to cook down the spinach.
CHICKEN: Chicken tenderloins (mini fillets) are the most convenient, but sliced chicken breasts can be substituted if tenderloins are not available.
DRAINING JUICES FROM TOMATOES & SPINACH:It is important to remove the excess liquid or the end dish will be watery. I do this using a sift. Sometimes I feel the spinach still requires more liquid to be removed and so I place the spinach in a clean dish cloth and squeeze out the liquid. (See post for images of this step). Don't throw away these juices, save them to add to smoothies or sauces.
MAKING IN ADVANCE: If preparing this dish to cook later, or to freeze, then the chicken tenderloins should be completely cooked before they are layered with the rest of the ingredients.
