If you can't find sweet piquanté peppers(aka Peppadew), substitute with sweet or dill pickle relish. They're traditional add-ins for classic macaroni salad. **Peppadew is the brand name of sweet piquanté Peppers from South Africa. They look like a cross between a cherry tomato and a very small red bell pepper and depending on how they're pickled, they come in mild and hot version. Find them at your grocery store or gourmet market. They're great on a cold antipasto platter.
