FAQs

What toppings can you add to fajitas?

Add sliced avocado, fresh salsa, sour cream, shredded cheese, fresh or pickled jalapenos, guacamole, iceberg lettuce, red onion, or chopped cilantro for additional flavor. Just be sure to check the carbs if you are following a strict low-carb or keto diet. If you’re on a dairy-free diet, choose a coconut-based yogurt instead of a dairy-based one.

Can I use only green peppers instead of red, orange, or yellow?

Yes, but colored peppers like red, orange, and yellow have a naturally sweet taste, whereas green peppers are slightly more bitter. Bell peppers change color as they ripen and colored peppers have matured longer on the plant.

How long are chicken fajitas good for?

Store the leftovers in the refrigerator and use within 4 days. Reheat before serving.
