Made this a bunch of times and it's purty easy.  Didn't like  the sauce though, so . . .
I used 1/2 cup regular mayo, juice of 1 lime, 1/4 cup of a roasted red pepper/eggplant spread (available at Trader Joe's although, you could just use roasted red peppers) and a healthy spritz of Sriracha hot sauce.   Fabulous with the shrimp.
I also like to serve it alongside a handful of frisee or peppery greens like baby arugula, watercress or mache in a cilantro-lime vinaigrette. The greens really help balance the dish.

In a small bowl, whisk together lime juice, olive oil, salt & pepper and set aside.  Add cilantro, adjust seasoning and toss with greens.
