Grilled Tuna Sandwich

Portillo's

Serious Eats
The firm fish gets a flavor char from the grill [...] with the sweet bun, crunchy lettuce, and sharp red onion playing a supporting role
Serious Eats
Instead of a standard tuna salad sandwich, Portillo's uses a tuna fillet, which is grilled so it picks up some nice charred flavor. The sandwich absolutely trounces the fried halibut fillet, which is just a step above a Filet-O-Fish.
