Store-bought crepes can be found in the refrigerator case at most supermarkets and gourmet food shops, and they are a wonderful short-cut to preparing a special springtime meal. These are filled with assorted vegetables doused with a bit of vinegar and soy sauce before baking and serving with a delectable sweet, tangy, and sour dipping sauce that's made from brown sugar, orange juice, and cider vinegar, among other ingredients. You can cook the sauce a day or two ahead of time and let cool before storing airtight in the refrigerator.
