Keep in mind it's leaf spinach, not that murky, grinded canned stuff like you'd see Popeye eat. I think any doubters would be overwhelmingly surprised as to how good it tastes when cooked in deep dish
. The iron taste associated with spinach dissipates when cooked and seems to add a certain sweetness. It totally melts in with the cheese so you won't find bits of green nestling between your teeth either. Try it!
