Heat a 12" cast iron skillet over medium high heat. Once hot add in the avocado oil to coat the skillet.
Add in the onion and bell pepper strips, oregano and salt and sauté for 10 minutes, tossing occasionally.
Serve immediately with your favorite Mexican-inspired dish!
Storage Instructions
Allow fajitas to cool completely, then transfer to a storage container for up to 4 days in the refrigerator, 3 months in the freezer.
Notes
Oven option: Preheat the oven to 450 degrees Fahrenheit, then bake for 30 minutes, tossing half way through. For the charred flavor and color, broil the fajitas for the last 1-2 minutes of roasting. Watch carefully so it does not burn!
Oil free option: Saute these veggies in water or vegetable broth instead of oil! Very similar result.
The less you stir the veggies, the better char they will get.
