Combine all of the ingredients into a gallon size zip lock bag. Be sure all the meat is coated thoroughly and let it rest between 2 hours to overnight.
When you are ready to cook your fajitas, heat your pan to medium-high heat with a tablespoon of avocado oil.
Remove the steak from the bag and place it in your pan, throwing away the extra marinade.
Cook the steak for about 4 minutes on each side. This can vary for how you like your steak cooked, but it doesn't need more than 10 minutes.
Serve with all your favorite fajita fixings and enjoy!
Notes
This marinade would go great with chicken too.
You can marinate the meat 2 hours to as long as overnight
You can serve this over a salad or in any tortilla you like.
