I'mma drop my knowledge on the subject, but not necessarily to defend some racist youngster.
Only time I ever ate garbanzos was on top of an italian salad.
Until I recently went to a little town in Michoacan where the wifey is from. In their plaza, they be slangin hot ass garbanzos. The cook em up in a wok type mechanism with butter and salt.
I also seen em being sold at the soccer game in Guadalajara.
Fuckin shits are GOOOOOD.
I was only asking the kid how he makes 'em to see if he was doing it right.
They remind me a lot of edamame, but with butter and salt on 'em.
I recommend you try them if you see them being cooked the way I'm talking about.
