1: Marinate the fish with lemon or vinegar and let it sit for 15–20 minutes, then wash it.
2: Make slits in the fish, then marinate again with all the ingredients listed under '2nd marinade.'
3: Optionally, insert whole green chilies into the slits.
4: Prepare the potatoes and place them on a baking tray.
5: Place the marinated fish on top of the potatoes.
6: Drizzle with olive oil.
7: Bake at 350°F for 40 minutes, then broil for 5 minutes to get a nice char on top.
8: Tip: Boil the sweet potatoes for 3 minutes before baking to help them cook faster.
