Preheat a large skillet (or wok if you have one) over medium-high heat with about 2-3 tbsp of avocado oil. Add in cabbage, carrots, onions and ginger. Saute for about 8-10 minutes stirring occasionally.
Move vegetables to the side of skillet, add steak and garlic to skillet and cook until steak is almost cooked through.
Stir in coconut aminos, fish sauce, sriracha and a pinch of salt while combining vegetables and steak together. Cook until steak is done.
Taste stir fry to see if you need more salt or coconut aminos. Serve over cauliflower rice.
*Nom Nom Paleo also has a great sriracha recipe if you don't have the Whole30 Fast & Easy cookbook.
**fish sauce has a lot of salt in it, so adjust how much salt you use accoring to your taste preference
