How should I serve sheet pan chicken fajitas?

The method of serving is completely up to you, but some ideas are enjoying the fajitas on a salad, with a bowl of cauliflower rice, or with a low carb tortilla. Keep in mind, if you do go the low carb tortilla route, most brands you’ll find contain wheat, which some choose to avoid on a keto diet.

My favorite brand of low carb tortilla is Mama Lupe’s Low Carb Tortillas. They’re only 3 grams of net carbs per tortilla and super delicious. They’re literally always my go-to, so I highly recommend them.

Some people following a keto diet choose to avoid vegetables like peppers and onions because they are higher in carbs, but in my opinion they’re not high enough to be completely ruled out.
