I had never put raw green onion in my burgers until Nash’s family made us burgers for dinner one day and included them in the toppings. They had stocks on a tray and I was like “What do I do with this?”. Then I put them in my burger.
It’s no strange than putting regular onions on your burger except it adds a fresh herb taste. Now I like to occasionally do it on burgers I make.
Do you put green onion in your burgers?

Nope, weirdly I don’t like the eating onions although I like the flavor it imparts in dishes.. so I would use it to cook in dishes but pick them out before eating..
