Prep Tips:

Fish: Use cod or other mild white fish like haddock. If needed, you could use pollock, tilapia, or catfish.
Shortcut: Swap in frozen breaded fish fillets to save time.
Cheese: American is classic; cheddar, Colby Jack, or pepper jack also work.
Buns: Hamburger buns, brioche, or potato rolls all hold up well.
Storage: Keep fish separate from buns/toppings; refrigerate up to 2–3 days.
Reheat: Oven or air fryer at 350°F for 8–10 minutes to keep it crispy.
