Place sliced beef, sliced onions, and green onions into a plastic zip-top bag. Add gochujang, soy sauce, ginger, garlic, sweetener, sesame oil, and sesame seeds. Squish the bag well to get the meat and sauce to incorporate well.
Allow the beef to marinate for 30 minutes or up to 24 hours in the refrigerator.
Place the meat and veggies into the air fryer basket. Set air fryer to 400°F for 12 minutes, shaking halfway through.
To serve, place a little meat in the tortillas, top with green onions, cilantro and kimchi if using, and serve with lots of napkins for this messy, but very satisfying meal.
*Nutrtion info does not include flour tortillas
You can use corn tortillas to make this a gluten-free dish.
You can opt to use lettuce leaves in place of tortillas to make this dish low carb.
You can also serve this with steamed rice (or cauliflower rice) and sautéed bok choy for a change.
This is a great recipe for meal planning! Just get the meat marinating and throw it in the fridge the night before and it will be ready to cook the next day.
