HI, Lovelies! It’s meeeeee! Happy Sunday!!

How was your long weekend? I hope you all had a wonderful time!
Are you hungover? I am, except that my hangover is a food-hangover. I purposely didn’t eat any potatoes or bread – all I wanted was meat. The carnivore in me had to come out. Later that evening I hung out with my buddies, Mojito and Chardonnay. I love their names…

Because I’m still in that holiday-food-mood, I’m inhaling a DQ Sundae as I’m typing…
Remember? Weekend calories don’t count.

Umm, are you ready for Monday?! (EWW!)

Hmmmm. So, what do we have here?!

OH! It’s just some jumbo stuffed shells with really good Florentine-ian (what?!) food!

I had this box of jumbo shells sitting in the pantry for, like, months. Not sure what I initially wanted to do with them, but when the almost-wilted spinach called out for me from the crisper drawer, I quickly found a solution to them shells.

This dish is so amazing because it can feed an army, and because of its very few layers of ingredients and flavors.  There’s tomatoes, there’s spinach, lots o’ garlic, meaty mushrooms, and a drizzle of a really, really good olive oil. If, for some reason, you are not a fan of mushrooms (what?!), leave them out. You can add ground meat instead, but I would suggest to reconsider – ‘shrooms are good!

And, in case you were wondering, Florentine is just a fancy way of saying “prepared with spinach”. And prepared in Florence?? Possibly?

    Mushrooms are so good! Despite being a cheese fan I had never cared for the usual ricotta filling unseen in stuffed shells but I dig this. Btw your pal Mojito has been hanging out with my pal Manhattan;)

    Haha I love the “what?!” for the mushrooms-who does NOT love mushrooms? Weird! :-)

    This dish looks awesome-people at work thought I was Italian because of all the pasta I always bring lol.

    Stuffed shells can make a pretty impressive pasta dish even though the ingredients are pretty straight forward. I really should buy a package one of these days.
