These vegetarian fajitas are soooo delicious and so easy. They’re made in one pan in under 25 minutes, perfect for busy weeknights.
Why are these the best vegetarian fajitas ever? Because they taste amazing but are so quick and simple to make. I mean, they’re ready in 25 minutes and only use one skillet. It doesn’t get much better than that!

Ingredients For Vegetarian Fajita
What goes into that skillet? Quinoa, black beans, diced tomatoes, bell pepper, onion, and smoked paprika. Then at the end of cooking, you top it with cheese and let that melt. To serve, you pile that delicious, cheesy, protein-packed, vegetarian filling into tortillas and top it with your favorite fajita toppings (things like sour cream, pico de gallo, shredded lettuce, diced avocado. You get the idea).
The best thing about these, even better than everything else I said, is if there are leftovers. Then I just put the lid back on and pop it into the fridge. Dishes done. Ha!
Using Leftover Fajita Filling
But seriously, the leftovers are great. You can use them as the base for a dinner bowl kind of thing for dinner later in the week. Or put a little pile of the quinoa filling on your dinner plate as a great side dish. Finally, this can be turned into a really quick soup for the thermos for lunch the next day if you heat it along with some broth.
Important Quinoa Tip
First, as to the quinoa, you really do need to rinse it. I say this to you especially if you’re someone who is only so-so on quinoa. I did a taste-test recently comparing cooked quinoa that had not been rinsed prior to cooking to cooked quinoa that had been rinsed, and there was a big difference. In fact, a further taste-test comparing quinoa that had been rinsed for 30 seconds compared to rinsing for 2 minutes and compared to rinsing for 5 minutes found that the 5 minute rinse was definitely the least bitter. The bitterness comes from the saponin, a dust on the outside of the quinoa seed.
To rinse your quinoa, put it in a fine mesh sieve and then use the spray nozzle from your faucet to get that more forceful spray onto the quinoa. Spray for 5 minutes while rubbing the quinoa between your fingers too. To read more about rinsing quinoa, and my other tips for making quinoa delicious, head over here.

I love this recipe!! So versatile and incredibly easy to make. It makes enough to last me an entire week and then some. I passed it along to my brother(a picky eater and beginner cook) and he has given it rave reviews despite the fact that he is a meat lover and frequently complains when a dish is lacking meat. I add extra chili powder and green chiles for a little more flavor and spice but overall this is one of my proudest discoveries thank you for sharing!

I’ve just been recently introduced to quinoa, and this looks like an easy recipe to use it in, thanks!
Christine Pittman says
It is easy andmy kids like it a lot (probably because of the cheese). Let me say this though, even if your box of quinoa says that you don’t have to rinse it before cookingit, still rinse it. There is sometimes a bitter-ish taste that seems to come from a powder on the outside of the grains. I’ve had bad-tasting quinoa from not rinsing a couple of times now and have decided that it’s just not worth skipping that step. Can’t wait to go check out eveyrone else’s #BackToSchoolWeek posts. Yum!
