Fajita night is a favorite in our house. I like to mix it up with different proteins but steak is always a winner with my family. This Homemade Taco & Fajita Seasoning adds tons of flavor without the additives found in store bought seasonings. I love fajitas because they are versatile and customizable. I can serve them as a salad, in tortillas for the kids, or over cauliflower rice for myself. Just add all your favorite toppings and enjoy!
Easy Sheet Pan Steak Fajitas are a great weeknight meal but also prefect for meal prepping. If you’re cooking for one or two this meal can be portioned into individual servings for lunch all week.
