Trim the outer leaves and soft stems off the cauliflower. Then cut 4, ½ inch thick, slices of the cauliflower head, lengthwise.
Rub the cut steaks with the garlic, onion, and ginger (use more if necessary).
Heat a large greased grill pan (you can also use a normal grill or any grill you have!) over high heat.
Once hot, place the steaks on the grill and grill for 8 minutes. Flip them and grill for about another 8 minutes.
To make the sauce, mix together the tahini, coconut aminos, and chili paste.
To serve, plate the cauliflower steaks, drizzle on the tahini sauce, and top with black sesame seeds!
