Start by marinating your fish with all the ingredients listed “for the fish marinade” — allow this to marinate for at least 15 minutes or overnight.
To cook, add 2 tablespoon cooking oil to a large skillet or pan over medium-high heat.
Add your green onion and white onion. Cook for 30 seconds.
Add your marinated fish and allow to cook for 9-10 minutes (or until the fish is fully cooked).
Add your dill and turn off the heat. Stir to combine and top with roasted peanuts.
Serve this fish hot with a side of rice vermicelli noodles, fresh Vietnamese herbs, and Mam Tom sauce (mix of shrimp paste, lime, thai peppers, and sugar)
