FAQs

1. Can I make these fajitas gluten-free?
Yes! Just use corn tortillas instead of flour tortillas for a gluten-free option.

2. What can I use instead of portobello mushrooms?
If you don’t have portobello mushrooms, you can use other types of mushrooms like cremini or shiitake, or even grilled eggplant for a different taste.

3. Are these fajitas spicy?
The spiciness level can be adjusted based on the amount of chili powder and optional hot sauce you choose to add. If you prefer less spice, use less chili powder or skip the hot sauce.
