Place the steak tips on a paper towel lined plate and pat dry. Place the steak tips in a single layer in the basket of your air fryer, leaving space in between each steak tip. Season lightly with the sea salt. Air fry at 380° F for 4 minutes. Remove from the air fryer and flip the steak tips over. Air fry at 380° F for 4-5 minutes more. This cooks the steak tips to about medium, but cook according to your preference and use a meat thermometer to gauge temperature.
While the steak tips air fry, prepare the sauce. Add the sesame oil to a small saucepan over medium low heat. Add the garlic cloves and saute for 1 minute until fragrant. Add the dried ginger and mustard powder and stir constantly for 1-2 minutes. Add in the coconut aminos, tahini, and date syrup. Use the spoon to break down the tahini and stir until sauce is well combined. When slightly thickened, remove from heat and pour into a large bowl.
When the steak tips are done, add them to the bowl with the Garlic Sesame sauce. Toss to coat the steak tips.
Serve hot garnished with sesame seeds if desired and enjoy! I like serving mine with rice (use cauliflower rice for Whole30) and steamed broccoli for a delicious "fakeout" meal.
