Slow Cooked Steak Fajitas

Healthy Slow Cooked Steak Fajitas

Let me just put this out there – I LOVE my slow cooker! Yes. There is nothing like taking a few minutes in the morning to throw together dinner, pop it in the slow cooker and let it cook away. No muss, no fuss. I get to enjoy some quiet time in the afternoon and when the boys woke up from their naps, its nice to not have to think about dinner!Slow Cooked Steak Fajitas

These healthy slow cooked steak fajitas are 21 Day Fix and 21 Day Fix Extreme approved and they are AMAZING! If you are on the Countdown to Competition plan, you can still enjoy this meal, just don’t add the optional toppings. I usually enjoy mine in lettuce wraps and my husband and boys love theirs in a tortilla – either way, they are delicious! I top mine in lettuce wraps with some Sriracha (hello spicy!!) I make Basili’s in a whole wheat tortilla with some no sugar added salsa and cheese.Slow Cooked Steak Fajitas

I hope you enjoy these as much as we do! A healthy, hearty meal that is full of flavor is sometimes just what the doctor ordered!

Serving Suggestions
  1. Make a clean Fajita bar! Whole wheat tortillas, lettuce leaves for wraps, plain Greek Yogurt, no sugar added salsa, hot sauce, avocado and shredded cheese.
  1. Heat up a skillet. Brown a whole wheat tortilla, flip and fill half of it with the fajita steak and peppers, top with cheese and fold over until cheese is melted and tortilla crisps up. (Fajita-dilla!!)
21 Day Fix Containers
  1. 1 1/2 cups= 1 Red, 1 Green (measure meat in red container and veggies in green container if possible - this will ensure the highest level of accuracy!) If you add toppings, count accordingly and make sure you don't go over on your blue containers!

    I didn’t know soy sauce was on the approved 21 Day Fix meal plan?

    1. Angela Dimitrelias

      Hi Bobbi! I had changed it in the ingredients section and now have it updated in the instructions. 🙂 Use liquid aminos. 🙂

  2. Joe

    Are you saying two full bottles of brags?

    1. Angela Dimitrelias

      Hi Joe! Nope! Just 2 Tablespoons. 🙂

  3. Jackie

    How many servings is this for? I am making meal for 10 people and they are all mostly on 21 day fix program

    1. Angela Dimitrelias

      This serves 6. 🙂

  4. Diana

    Following the container sizes for 21 Day Fix, how many servings will this supply?

      6 people

  5. Katie

    You don’t add any other liquid to this?

    1. Angela Dimitrelias

      I did not. You CAN if you feel it might be too dry. The juices from the meat were PLENTY!

  6. Liz

    HI! How many servings does this make???

  7. Liz

    Never mind! I just saw 6. 🙂 Thank you anyway!!!!

  8. Colleen

    How long if this recipe is cooked on low?

    1. Angela Dimitrelias

      I would think 7-8 hours on low.

  9. Kelly

    Won’t the peppers get all soggy and over cooked?

    1. Angela Dimitrelias

      They are not crisp/crunchy at serving – if you like them that way, I would leave them out and maybe make your peppers on the stove top, separately.

  10. Kimberly Patterson

    hi, did you use flat iron or flank steak in the picture? I tried to cook one of these type meats on the stove top once, and it was so tough!! so let me know what cut of meat you used 🙁 I would love for mine to look like yours. So did you put it on high or low all day in crock? thank yoU! 🙂 kp

    1. Angela Dimitrelias

      I used Flat Iron. 🙂 The Flank steak is too tough for my family’s liking. 🙂

  11. Pam Mitchel

    could you use a deer roast?

    1. Angela Dimitrelias

      that is a good question – I have never cooked deer roast, so I am not sure how they compare…I bet someone who reads this will!
