This is a recipe from the Kikkoman's Kitchen that I have been wanting to try for awhile. I didn't have the Ponzu Lime Sauce for the remoulade so I improvised and made my own with soy sauce, rice vinegar, water, sugar, and True Lime (dried lime crystals). We added sliced tomatoes and passed the bottle of tabasco around the table. These spicy and crunchy shrimp sandwiches were a huge hit.
