In a large pot, bring water to a boil and add a pinch of salt. Add the shrimp and cook for about 2-3 minutes or until they turn pink and opaque. Drain and rinse under cold water to stop the cooking process.

Mix the Ingredients

In a large bowl, combine the cooked shrimp, tomato sauce, ketchup, and lime juice. Mix well until the shrimp are evenly coated.

Add Vegetables and Seasoning

Add the finely chopped red onion, cilantro, diced avocado, and jalapeño to the shrimp mixture. Stir gently to combine. Season with salt and pepper to taste.

Chill and Serve

Cover the bowl with plastic wrap and refrigerate for at least 30 minutes to let the flavors meld. Serve chilled in individual cups or bowls.
