Prepare the Seeds:

1. If the pumpkin seeds are not already roasted, roast them in the oven until they are golden brown. Once cooled, grind them into a fine powder.

Add the Chili Peppers:

Cook the Seeds:

Simmer:

Add the Fish:

1. Add the deboned smoked fish pieces to the pot and stir well. Continue to simmer for another 10 minutes.

Season and Serve:
