Spinach is a great supplier of iron to the body.
More than that, it also supplies, when cooked, vitamins A and E, protein, fiber, zinc, thiamin, calcium.
I use spinach whenever possible, especially as a sandwich base.
It goes well with many other ingredients like eggs, cheese, bacon, and more.
It also receives well several condiments and spices.
You should try, you won't be disappointed.
