Slice the jumbo scallops thin, about 3 or 4 pieces per scallop. Slice the octopus on a slight diagonal as thin as you can. Place seafood in a bowl, add lime juice and toss well. Refrigerate for 10 minutes; you only want a slight “pickle” here since scallops are also delicious raw.
Drain the lime juice from the scallops directly into a blender jar. Add 2 tablespoons of Mijenta Blanco. Add chiles, cucumber, cilantro, parsley, salt, and purée until very smooth, about 3 minutes. Strain.
Divide scallop/octopus mixture among six small bowls, piling into tall mounds. Divide the cucumber liquid among the bowls. Garnish with radish, avocado, cucumber and red onion, and serve with tortilla chips.
