I've made snello with the addition of deshelled raw shrimp whizzed in the food processor (along with cooked peas, gelatin, etc). It was a big hit except I didn't add enough gelatin, so it got messy pretty quickly. After this batch of veggie snello is gone (not for awhile), I'll try some with some shrimp. But it's a bit awkward to be feeding shrimp to shrimp... but I guess they do scavenge their own dead...
