It goes without saying that Tex-Mex cuisine wouldn't be complete without fajitas. But when you live a vegan lifestyle or simply want to eat more veggies, this mouthwatering dish is literally off the table. After all, by definition, a fajita calls for grilled meat served on a tortilla. This doesn't mean you can't get in on the deliciousness, though! By cooking Portobello mushrooms in the right spices, you can enjoy a meaty texture with that classic fajita flavor. Add some cooked onions and bell peppers, and you've got yourself an easy vegan fajita recipe. Here's how to make it happen.

To construct a fajita, add the cooked onions, peppers, and mushrooms to a soft tortilla shell. Top off with tasty ingredients like vegan sour cream, guacamole, salsa, or a splash of lime juice. Even better, why not add all of the above?

Don't limit yourself to soft tortilla shells, though. Vegan fajita fillings taste just as delicious with pasta or rice. You can also toss them with greens and veggies for a fajita-inspired salad. Who wants seconds?
