These EASY Portobello Fajitas are a flavorful, satisfying weeknight meal. Plus they’re only 30 minutes, and you can also personalize them with your own favorite toppings!
We’ve been on the road a lot this summer (LOVE road trips!) and just got home from three incredible weeks in my favorite place on earth: Yellowstone! It’s like a magical wonderland where every day feels like a new, amazing adventure. The mountains, pine trees, and fresh air completely fill my soul and refresh my inner being. So after a much-needed break, I’m back in action combining a few of my very favorite things – mushrooms, Mexican food, and colorful plants!
How to Make Portobello Fajitas
These simple fajitas are such an easy, satisfying dinner (plus perfect for busy weeknights!) Simply saute the mushrooms & veggies with taco seasoning, and get your toppings ready in the meantime. Also, to prep this meal in advance you can even slice the veggies and make the taco seasoning ahead of time so it’s even easier to throw together come dinner time. (The recipe calls for two bell peppers but I used four different colors, taking half of each pepper for maximum rainbow effect.)
For different flavor variations, add garlic or chipotle, then personalize with your own favorite toppings (like avocado, fresh pico de gallo, or restaurant-style salsa!)
