Spinach, a delicious source of iron and calcium

I left Buenos Aires and moving on to San Luis, visiting some chilhood friends.
The weather is fantastic, warm with a nice breese keeping the day from becoming hot.
My frineds are so kind and happy and hospitable; I don’t want to leave.
“Vivi”has been working at my friends house for almost a decade and yesterday she made a fantastic spinach fritatta. She is the proud owner of some very expensive Essen cookware. Interestinly with that kind of pan you do not need to precook any of the frittata ingredients and you do not even need to turn it over.
Here she is sharing her recipe.
