Years ago I went to a popular restaurant and the served a Shrimp Verecruz. They eventually closed down and I tried for a long time to duplicate it. I believe I got as close to it as possible only because one year we had a family gathering and I brought this with me. My neice took a bite and said "Oh my gosh! This is just like the Shrimp Verecruz at Pancho's"
You can serve it as a dip with chips or as a main dish with refried beans and pico de gallo and chips on the side.
