Place all ingredients into a mixing bowl and whisk together.
For Steak Marinade
Set aside 1 ½ tablespoon of the fajita seasoning you’re going to reserve for seasoning the vegetables later then put the remainder of the fajita seasoning in the bowl.
In a mixing bowl, combine all remaining ingredients, whisk together to combine, and pour over steaks in a bowl or preferably a Ziploc bag. You will then place the steaks in the refrigerator to marinate for at least one hour.
Tequila Lime Steak Fajitas
To prepare, place the steaks whole into the marinade and place the container in the refrigerator to marinate for at least one hour before preparation.
Allow steak to reach room temperature before grilling to help keep them tender.
While waiting on steaks to reach room temperature Julian onions, peppers, and jalapenos to about ¼ inch thickness. Removing steaks from the marinade will allow them to reach room temperature faster. Discard the marinade after use.
Season steak with kosher salt and black pepper, then grill on high (if cooking with gas) or over direct heat if cooking on coals/wood, but if you don’t have a grill, you can cook the steaks in a hot skillet with a bit of oil.
Cook steaks to your preferred level of doneness. I prefer mine cooked to about a medium rare, depending on the thickness of the steaks, about 3 ½ to 4 minutes per side.
Remove from heat and allow steak to rest on the counter or cutting board while you sauté the vegetables.
Over high heat, place onions, peppers, jalapenos, and 1 ½ tablespoons of the fajita seasoning into a hot skillet and cook until vegetables are tender for about 4 minutes.
Slice the steak to desired thickness across the grain to help the meat stay tender. Place sliced meat into a pan with vegetables and remove from heat.
Grab a tortilla and ladle on some of your steak and peppers. Top with shredded lettuce, cheese, jalapenos, salsa, and sour cream if desired. Enjoy!
