Why make this recipe?
As the name implies, this recipe combines fajita and taco flavors and textures, all packaged together in a refreshing steak taco salad. Charred strips of bell pepper, jalapeno and red onion add the typical fajita flavors. Crumbled Doritos give the salad the crunch you get from a hard taco shell. Together this is a fantastic meal salad that has everything you want and need from a dinner in one big, delicious bowl.

What cut of beef should I use?
I recommend sirloin steak for this recipe. Sirloin steak has great flavor and is still quite budget-friendly. That being said, you can also go with higher quality cuts of beef, such as rib eye, if you want to.
I don't recommend cheaper cuts of beef, such as steak cubes labeled as "stew meat." This cut of beef will be very tough after frying and does not have much flavor.
How to prepare beef and vegetables:
See full ingredients & instructions in the recipe card below!
Step 1. Slice red bell pepper, jalapeno and red onion into thin strips. Set aside.

Step 2. Cut the steak into ¾-inch to 1-inch chunks and season with salt and pepper. Set aside.

Step 3. Heat olive oil in a cast iron pan until very hot, then sear the steak bites in it. Transfer the steak to a bowl using a slotted spoon. Add the vegetables to the same pan (no need to clean it in between) and cook until starting to soften.

Super fast and super easy to make.
We cut our steak into strips rather than cubes. In our house, this fed two adults, but fell just shy of 3 adult portions. I recommended multiplying the recipe accordingly, depending on the size of your family.
