1 lb peeled and deveined medium shrimp
1 cup fresh lime juice
6 plum tomatoes, diced
1 large red onion, cut into thinly sliced strips
2 avocados, diced (optional)
1 jalapeno pepper, seeded and minced (optional)
chopped fresh cilantro to taste
salt and pepper to taste
1. Place shrimp in a glass bowl and cover with lime juice to marinate (or 'cook') for about 10 minutes, or until they turn pink and opaque. Meanwhile, place the plum tomatoes, onion (and avocados and jalapeno if using) in a large, non-reactive (stainless steel, glass or plastic) bowl.
2. Remove shrimp from lime juice, reserving juice. Cut into chunks and add to the bowl of vegetables. Pour in the remaining lime juice marinade. Add cilantro and salt and pepper to taste. Toss gently to mix. Serve immediately or refrigerate, the longer it sits, the better it becomes.
