Season fish with lime juice, salt and pepper. Cook fish on stove until white and flaky. To make white sauce: In a medium bowl, mix together yogurt and mayonnaise. Gradually stir in fresh lime juice until consistency is slightly runny. Season with jalapeno, capers, oregano, cumin, dill, and cayenne. Top with cabbage, cilantro, or other desired topping. Great with mango salsa.
These fish tacos are to die for.
