Prepare the spinach mixture:
For frozen spinach: 8 ozs in the microwave (no water) on high for 4 minutes. Then press out all the excess water in mesh strainer using the back of a large spoon, the drier the better.
In a fry or saute' pan, add 1 teaspoon Canola oil and a diced onion, and cook for 2 minutes until clear. Add 1/4 teaspoon of red pepper
flakes. Add spinach. Salt a slight bit saltier than you would to compensate for adding the mixture to the other ingredients in the next step. Cook on low until there is no moisture left. Spoon out the spinach and lightly arrange in the bottom of the baking dish.
OPTIONAL: You have the option to add mushrooms or small pieces of artichoke as additional vegetables while cooking. Recommended amount is 1/4 cup, chopped.
FRESH SPINACH PREP: 3 packed cups of fresh spinach, into the saute' pan on top of the cooked onions on low heat, turning until they wilt. Do not cover, just turn them until they are wilted. The object is to keep them dry. You don't want any liquid.
