Oh, my goodness, the idea and image of this recipe have certainly got me drooling and anticipating the day I try this beautiful dish! Spinach and caramelized onion are already an amazing combination by itself in my book...but adding egg and cheese is definitely going that extra mile that makes me a happy girl. I've never heard of putting aluminum foil on the handle of a pan before putting it in the oven, and now I'm wondering what the purpose of this is?

I love spinach, but the medication I'm on (blood thinner) requires me to restrict the amount I consume. Still, this recipe looks really yummy and simple to make, and I'm sure I could have a piece or two without much trouble. My wife loves spinach as well, so it's definitely something we'll try. Thanks for the hint about using feta cheese. Is that in addition to the cheddar, or in place of it?

Whenever I see the word caramelized I know I have to take a look. I love frittatas as they are an easy, substantial meal and I love onions so all three of these are great in my book! I can't wait to try this recipe. I am also a big fan of spinach and I agree it is a good source of iron but we need magnesium to absorb iron properly so I would add in Feta cheese to this recipe to get the magnesium.

This breakfast looks sooo good I cain't wait to try it.
