Cut the beef into bite sized pieces. Mince the ginger, garlic, and date (if using). Whisk together all the marinade ingredients. Lay the beef in a shallow rimmed dish, and pour the marinade over the beef, turning to coat. Cover and marinate for at least 30 minutes.
Do the Prep Work
Preheat the grill to medium-high, about 450F.
Halve the mushrooms and cut the asparagus into 3-4 inch pieces. Thread the meat, asparagus, and mushrooms onto the skewers.
Cook the Kebabs
Once the grill is hot, lightly spray or brush with oil. Lay the skewers on it, leaving a little room between them. Grill, turning to cook all four sides, for about 2-3 minutes per side for medium.
Set them aside and allow them to rest. Meanwhile, slice the green onion and sprinkle them on top of the skewers.
Season lightly with salt and pepper and enjoy!
Notes
To make this recipe Keto, simply omit the date from the marinade. You could substitute a low carb sweetener if you'd like or just leave it off completely. Some tips:
Leave room on the skewer.
Use thicker asparagus.
Cut the meat and vegetables into true bite-sized pieces.
If using wooden skewers: Soak them in water for 30 minutes to an hour first. It helps keep them from burning while the kebabs cook on the hot grill.
