Grilled Beef Fajitas for Cinco de Mayo

Grilled Beef Fajitas with Mango Salsa, Grilled Balsamic Onions, Lime Yogurt, & Guacamole

Cinco de Mayo is tomorrow. Although we’re in lock down and social distance ourselves from others, it doesn’t mean can’t celebrate at home.

My immediate family got together yesterday evening to do just that, in our backyard.

The weather was ideal for grilling since the rest of the week calls for rain – so it was perfect!

We are huge fans of fajitas, and this recipe is so simple there’s no excuse not to try it – unless of course you don’t eat meat.

I love my new FabSlabs serving board, and try  to find reasons to use it constantly.  Plus it’s great for loading everything up and bringing all the goodies to the table in one swoop!

I paired my Grilled Beef Fajitas with Grilled Balsamic Onions, Fresh Lime Yogurt, Guacamole, and Mango Salsa.  Each takes no time to prepare, and most can be made and prepped ahead of time.

Serve with fresh fruit, and your favorite beverages and you’ll be a happy camper.  

Create our mango salsa, or jazz it up by adding in black beans or anything else that appeals to you.

If you love my FabSlabs board as much as I do, (it’s permanently anti-bacterial) you can order it in the U.S. or Australia.

Whether you make my Grilled Beef Fajitas for Cinco de Mayo or another night, be sure to try them – hands down, they’re amazing!!!

Take care & be safe during these uncertain times, and eat healthy!

  6. Serve steak, with grilled onions, and optional toppings if desired, in warmed tortillas.
