In a hot frying pan, sauté the chopped onion and minced garlic in the olive oil until they become transparent. Add the shrimp and cook for 1 minute. Add the chipotle chile, white vinegar and salt. Cook for 1 more minute, and remove from heat.

Take the GUERRERO® Tostadas Caseras Amarillas and spread 1 tablespoon of beans on each one. On top of the beans, place 1/4 cup lettuce and add the shrimp. Serve with the marinated onion.
