Fix Approved Cheesesteak Stuffed Peppers

A healthy take on this Philly favorite, my Fix Approved Cheesesteak Stuffed Peppers were a huge winner at our house last night. My (bread-loving) husband thought it was delicious and didn’t (SEEM) to mind that there wasn’t a bun. I typically have sandwiches with out the bun (so is it REALLY still a sandwich??) anyway so this was right up my alley.  If you are like my good friend, Mandy, and dislike (HATE) mushrooms, I would suggest swapping out the mushrooms with some thinly sliced and halved zucchini – just replace the word mushroom with zucchini in the recipe. 🙂

This ooey gooey indulgence was melt in your mouth DELICIOUS!! I love steak and veggies and ANYTHING topped with cheese is a must try in my book! (Save all the blues!!) Simple and delicious (and easy to serve!) You can make this one ahead of time and pop it in the oven when you are ready for dinner.

    Does this serve four or two people?

    1. Angela Dimitrelias

      Hi Leslie! This recipe serves 4 people. 🙂

  2. Elizabeth

    Can this be made in the crock pot? I don’t have an oven.

    1. Angela Dimitrelias

      Hi Elizabeth! Do you have a stove top? You could skip the oven part and finish it all on the stove, cover until cheese melts. Otherwise, I would cook the meat in the crock pot and maybe even add in the peppers sliced with everything else – you could make it like a one pot meal vs actually stuffing the peppers. I have thought about doing this recipe that way and then topping what is on my plate with cheese and allowing it time to melt before serving. Let me know if it works for you! xoxo Angela

    Hi Angela,

    You mentioned in your post that these could be mad ahead. I want to make these today for dinner tomorrow. Do you see any problem with that?

    1. Angela Dimitrelias

      Hi Tracy! Sorry I am just seeing this! I think that would be just fine – I would make and assemble and then bake them the next day for dinner. 🙂

    How do you get your steak so thin?

    1. Angela Dimitrelias

      Hi Tracy – sharp knives! 🙂 I use Flat Iron Steaks and slice them up before cooking. Enjoy!

    2. Mary

      If your steak is partially frozen, it will be easier to slice thinly.

    I’m making these tonight with leftover pot roast. LOVE 21 DF recipes so thanks!!!

    1. Angela Dimitrelias

      Yum! Enjoy! I am making these tonight at our house!

  6. Heather P

    Do you mind if I share this recipe on my blog (linking this page,of course)?

    1. Angela Dimitrelias

      Absolutely! 🙂 Thank you!

  7. Maggie Slick

    This may be a dumb question, but how does one slice steak thinly like that? I doubt Steak-Ums are 21 Day Fix approved.

    1. Angela Dimitrelias

      I have a set of very sharp knives. They are one of my favorite tools in the kitchen!

    Hello Angela,

    Thanks for the recipe. This looks amazing. I’m starting the 21 day fix over again, the first time I didn’t quite finish.

    Just to make sure…
    Does both haves of the bell pepper count as a green container?
    Or, One half is a green?

    Thanks in advance,

    1. Angela Dimitrelias

      How exciting! 1 serving is 1/2 pepper stuffed with the meat. 🙂

  9. michelle

    Loved it! It was so fast to put together even after a looooong day at work. Thanks again for all your great recipes.
