1. In a nonreactive bowl combine the cubed fish, lime juice, salt and pepper; press the fish down so it is mostly covered. Cover and refrigerate until the fish turns opaque and is firm to the bite, about 20–30 minutes (taste after 20 minutes; longer for firmer texture). Drain off about half the citrus if you prefer a less liquid ceviche, reserving a little for flavor. 2. Add the sliced red onion, diced tomato, cucumber, minced serrano and chopped cilantro to the cured fish; drizzle with olive oil if using and gently fold in the diced avocado. Adjust seasoning with additional salt or lime to taste. Serve chilled with tostadas or crackers.
