Ingredients
Steak: I used two flank steaks for this. I like to use high-quality meat whenever possible. My favorite place to get meat is ButcherBox because they have organic and high quality options and it gets delivered right to your door! You can also feel free to substitute with chicken or another meat, if desired.
Peppers: I used 3 different colored bell peppers here. Feel free to use whatever colors you would like! You can also add additional vegetables, like mushrooms, if you wish.
Onions: I like to use sweet onions here, but feel free to use red onions as well.
Lime: I love using lime as part of the marinade for this! It adds a delicious zesty flavor.
Seasoning: I used Redmond Taco Seasoning here. If you use my discount code LESSWITHLAUR you can get 15% off their website. You could also make your own homemade taco seasoning.
Avocado Oil: I like to use high quality avocado oil. I love ordering all of my staples from Thrive Market because they have great prices and they deliver right to your doorstep. If you use my link, you can get 40% off your first order.
Sides and Additions: I used Siete Tortillas, avocado and refried beans as sides here. Feel free to add additional sides like pico de gallo, dairy-free cheese or dairy-free sour cream.
