These are like mini shrimp tacos. Wonton wrappers are baked in the oven until crisp, filled with arugula, a lime sour cream, and then topped with a big juicy chili-lime shrimp. You can make the wonton shells in advance, but assemble the cups with the arugula, sour cream and shrimp just before serving. See below in the notes section for more details. Another option for the cups is to use store-bought tortilla chips in the shape of cups, sometimes called scoops.
