Last year Taco Bell introduced its customers to the Pacific Shrimp Taco, a well-timed grilled shrimp menu item that featured six marinated and grilled shrimp, topped with shredded lettuce, avocado ranch and fiesta salsa in a soft tortilla. A year later, Taco Bell brings back this flavor in both taco and burrito format. The larger brother of the shrimp taco comes in a large soft flour tortilla, packed with the same marinated shrimp, shredded lettuce, creamy avocado ranch, fiesta salsa, a 3 cheese blend and crispy red tortilla strips. Ready for fish? So is Taco Bell, for a limited time only though.
