To make the marinade, combine:
*1/2 tsp dried oregano
*1/4 - 1/2 tsp dried chili powder (I used 1/2 tsp and did not find it too spicy)
*One scallion, chopped
*3 garlic cloves, roughly minced
*Juice of 1/2 lime
*1/2 cup roughly chopped cilantro
*1/2 cup olive oil
Salt and pepper your fish - I used about 1 1/4 lbs of cod - and then let sit in the marinade in the fridge for one hour.
When you're ready to cook, heat two tablespoons of olive oil in a pan and then pan fry, 3-4 minutes per side or until cooked through.
