Cod is a very mild salt water white fish that can be as large as 100 pounds. If properly prepared, the jalapeno peppers will provide great flavor and won't overpower the delicate flavor of the fish.
Ingredients:
4- 6 ounce pieces fresh cod
1 lemon
Kosher salt and freshly cracked black pepper to taste
1/3 cup bread crumbs
1 tablespoon extra-virgin olive oil
2 tablespoons jalapeno peppers, seeded, finely chopped 
1 tablespoon butter
1 tablespoons extra virgin olive oil
¼ cup queso fresco cheese
Instructions:
Squeeze juice of lemon onto each piece of cod, sprinkle with salt and pepper.
In a small bowl, combine bread crumbs, 1 tablespoon EV olive oil and jalapeno peppers.
Heat butter and 1 tablespoon EV olive oil in an oven proof medium skillet on medium heat. Add cod. Top cod with jalapeno bread crumb mixture. Sear for 3-5 minutes until bottom is golden brown.
Turn on oven broiler and place skillet under broiler and broil top of cod until top of bread crumbs are slightly brown. Remove from oven, top with cheese. Turn oven off, put cod back under broiler just long enough to heat the cheese. Serve over couscous.
