Yes. My dad likes the grilled greenback mackerals. If you want to try them professionally cooked, go to Tajima on Convoy and order the Saba Shioyaki.
I am not a fan of greenies, but the Spanish Macks make great sashimi and I do like those. I keep them regularly as well as order them in restaurants. Better than yellowtails IMO. They sell them at Sushi Ota in PB for $17 per mackeral. An order of spanish mack sushi is more expensive than an order of yellowtail belly sushi.
