Lately, I’ve been craving vegetables any way I can get them.

I want them for breakfast, lunch, dinner, roasted, stir-fried and/or in salads. And today I had the BEST vegetarian fajitas! I tucked thick slices of fajita-seasoned portobello mushrooms into toasty-warm yellow corn tortillas and topped it with charred peppers onions and fresh avocado, tomatoes and torn cilantro leaves. It was pretty spectacular.

I’m seriously considering a vegetarian diet, but I think I’d miss bacon too much.

Next, heat 1 tablespoon of oil in a large, 12-inch cast iron skillet over medium to medium-high heat until it glistens. Then add in all of the peppers and onions in at once and season with a generous pinch of kosher salt.

Next, toss the vegetables around to coat in the oil and then let them cook, undisturbed for 3 to 4 minutes.

Quickly toss and repeat until the peppers and onions have good char and have softened a bit but are still slightly firm. Next, transfer them to a bowl, cover with foil to keep warm and set off to the side.

Now for the mushrooms!

Meanwhile, wipe 12 ounces (about 4) Portobello mushroom caps with a slightly damp cloth and remove the stem.

Removing the gills is up to you. I leave them.

In the same skillet the vegetables were cooked in, add a teaspoon more of oil and add in the mushrooms. Cook on medium heat, tossing only occasionally until they are tender but still hold their shape and are a bit firm. Kind of like the peppers and onions.

Remove off of the heat and start building your fajita tacos.

While all of this was going on, I quickly warm these tortillas in a dry skillet, over medium heat. I just heat one at a time for about 3o to 40 seconds a side. For more of a crispy shell, keep them in the skillet a little longer.

Stack 2 to 3 portobellos onto a couple shells.

Top with the peppers and onions and any other topping your heart desires.

Lastly garnish with tomatoes, avocados, cilantro leaves and wedges of lime. However, I also like to serve jalapeños, pepper jack cheese and sour cream therefore dress these up however you prefer.
