ASAP Poke, which launched just last Tuesday, delivers the raw fish (salmon, tuna, etc.) in a salad with multiple ingredients and rice. Prices run in the low double digits (all under $12.95, and that includes delivery).
If the ingredients are in stock because they're included in dishes on the regular menu, you can have the people in the Francesca's kitchens mash up those ingredients in whichever way you want. Kind of like your own personalized off-menu item, which at first sounded kind of cool.
