Fennel is used as a pizza topping anyway, usually mixed with onion. I actually think fennel toppings are great and I recommend them. I haven't come across fenugreek or maca being used in this way, but I take the view that anything you want to be a pizza topping can be a pizza topping.

Haven't heard about fennel topping as well. Maybe it's more american thing or because I usually cook pizza myself and don't know about new things they do with pizzas at restaurants. Next time when I'll cook pizza I'll try to make it with fennel topping.
