Seared fish tacos; what types of fish? (cheap-ish)?
I'm making a spice mix for my tacos and searing so I'll near a fish that's common enough I should find, but also somewhat cheap (No swordfish). I can also filet my own fish, so size isn't that big a deal.
Should I go for mackerel, snappers, basses (moderate activity fish), or go for flat fish? What about Halibut?
Bonus: Is it likely that flat fish are served seared, or should they preferably broiled due to low fat content.
