Mexican food is one of my favorites and I’m surprised I have more cookie recipes on my blog than I do Mexican food recipes! We eat Mexican food at least once a week for dinner and then I eat it three times a week for lunch.

I will whip up a batch of my favorite vegan queso and use that all week. These Portobello Fajitas are so delicious and are a great way to incorporate more mushrooms into your diet.

Simple Customizations

Make these portobello fajitas your own by replacing or adding a few simple ingredients. Here are some of my favorite customizations:

  • Black beans
  • Any color bell peppers you have on hand
  • Corn
  • Any onion you have on hand. Red onions are a bit sweeter but if you have a lot of yellow onions on hand, use them!

Delicious Sides

These fajitas are filling on their own however, you can always stretch them out by serving up a side or two! I love to serve side dishes with this recipe:

  • Spanish rice
  • Vegan unfried beans
  • Corn salsa
  • Cowboy caviar
  • Chips and guacamole
