Shrimp and Mango Adobado Salad with Grilled Corn-Avocado Salsa

Shrimp and Mango Adobado Salad with Grilled Corn-Avocado Salsa
This recipe is a reinvention of a classic dish. Remember when salsa was made only with tomatoes? This lively corn-red-onion-avocado-pepper salsa goes with grilled shrimp and mangoes, which are briefly immersed in a snappy grapefruit-lime juice marinade.
