Axe's is description, is on the money, in my experience!
The sizzler dish, put directly on the hob (High Heat)
raw onions placed on top, Chicken Tikka placed on top of onions
blasted with heat then a couple of squirts of lemon dressing, to get it
sizzling and smoking.
In this restaurant, no additional spices are used with the onion.
Here's a similar example, but for mixed kebab and in this one the big chunky onions and capsicum are deep fried till almost cooked, then arranged on the
sizzler before being blasted.
