In a small bowl combine red onion, lime juice, olive oil, pinch of salt and pepper. Let them marinate at least 5 minutes to mellow the flavor of the onion. In a large bowl combine chopped shrimp, avocado, tomato, jalapeno. Combine all the ingredients together, add cilantro and gently toss. Adjust salt and pepper to taste.
