Spinach Po’Boy

    I made this for my family last night and got great reviews. This is a vegetarian dish I love, My daughter is vegetarian! I used red onion because that is what I had on hand and I think it made it eve better. My daughter called it a bougie grilled sandwich, which t was!

    Mmmm, so good! I made one sandwich and used sliced sourdough. So quick, easy and good! I like the dea of adding mushrooms, that would be a good addition.

    This is one of my favorites and have been making it for a long time. The only thing I change is not to add the hot sauce.

    We really enjoy these. I used about 4-5 cups of spinach, and that was enough for 2 servings. The spinach really wilts and shrinks down.

    I made this sandwich 2 nights in a row, it was delicious, I also added mushrooms, all I can say is yummy & nutritious. I also made baked sweet potato chips.

    Wonderful recipe! IF I want to make it a bit healthier, I MAY use olive oil instead of butter, but the spinach takes care of the "healthy" in my cookbook-mind! - and I use a bit more than the recipe calls for. I like "packed" sandwiches!! I love Artisan's Bread for this kind of sandwich, but will also use individual buns - even Kaiser rolls, as long as they're a wee bit crusty. Thanks for a great recipe - and helpful reviews, especially re using frozen spinach if that's the only spinach in the house!

     If it doesn't sound good to you, just look for a different recipe. I thought this was very good.

    I am usually a "meat guy" but the idea of "greeking" this up with some feta appeals very much and my wife is making this as I write. I've sampled the spinach filling with some cheese added (without bread) and been shoo-ed away. Quite delicious... I don't see how bread will detract from it so 4-stars for carnivores and one more star because vegetarians will love this. Most anyone is clever enough to make this more healthful if so desired.
