At a cute tea shop in ABQ, I had grilled shimp on top of parmesan nests with a bit of greens.
It was pretty simple. The nests were made using a mini-muffin (tassie) pan with large grated parmesan and baked...they ended up lacey. I've never made this...perhaps they nest another pan inside to keep the shape?
Shrimp was grilled and napped with a lemon remoulade.
Greens weren't dressed because of the shrimp sauce.
All very simple to prep ahead and tasty for a 2-bite appetizer.
