Beef Fajitas with Bell PeppersMexican Beef Fajita Skillet

Fajitas are the perfect meal as far as I’m concerned. They have a ton of flavor and no carbs. So I always feel like I can load up my skillet with lots of bell peppers and onions, still have the “beefy” flavor because they’re all cooked together and keep my points low. Lots of people love Lettuce Wraps and this beef skillet recipe is the PERFECT one for lettuce wraps.

To make the lettuce wraps even more delicious top them with some fresh cilantro, it brings out a great flavor and makes them taste so fresh.  And if you want to top them with greek yogurt but want to tame the “tang” I suggest adding a bit of hot sauce, fajita seasoning or even taco seasoning. You can also puree with fresh cilantro and a bit of green onion to mask the “yogurt” flavor a bit more.

We have other easy fajita recipes on the blog including Fajita Vegetables and Skinny Carne Asada which we love serving with Creamy Cilantro Lime Slaw.

Ways to serve Beef Fajitas:

  • With tortillas as originally intended. I use corn or low carb ones with lower smart points.
  • With a large salad full of romaine, grape tomatoes, avocados, salsa, fat free greek yogurt (or fat free sour cream).
  • Cook some cauliflower rice with some additional fajita seasoning and a bit of salsa. Top with the beef fajitas.
  • Rolled in a corn tortilla with sharp cheddar cheese, ff sour cream and baked with enchilada sauce.
  • In lettuce cups or even in red bell pepper cups (red bell peppers are so sweet I’ve gotten hooked on this!) instead of tortillas.

Homemade Fajita seasoning:

  • 2 teaspoons chili powder
  • 1 teaspoon salt
  • 1 teaspoon paprika
  • 1/4 teaspoon white sugar
  • 1 teaspoon dried onion flakes (you can substitute onion powder)
  • 1/4 teaspoon cayenne pepper (I use 1/2 teaspoon because we like a bit more spice)
  • 1 teaspoon ground cumin

Mix the ingredients together and store. This is good for 1-2 pounds of chicken/beef/fish.

Fun Fajita Vegetable Mix-Ins

  • MORE bell peppers.
  • Red onions instead of yellow, the sweetness is great and you can add as much as you’d like.
  • Zucchini (I cut these in strips instead of coins for fajitas)
  • Roma tomatoes cut into quarters lengthwise. Even better if you can cut it without exposing the seeds so they don’t get lost in the skillet.

Note: Just remember when you’re adding/bulking up the veggies you may want to consider making more of the fajita seasoning. You don’t want the flavors to become too muted.

  1. Tried it tonight, was really good! Forgot to get tortillas so I made some lime cilantro rice on the side and it soaked up the juices/ flavors really well. Really enjoying your recipes, thanks!!
