Summer Rolls are one of the great culinary inventions in the history of man. A perfect package of crunchy vegetables, fragrant herbs, and the soft but snappy bite of rice paper enriched with the sweetness of some sort of sauce. At Purple Mint Vegetarian Bistro I appreciate that they don’t dilute the rolls with extra noodles, offering rice paper stuffed with tofu, purple mint, lettuces, basil, jicama, and carrots.  The sauce, although spiked with crushed peanuts and pickled carrots, runs bland and benefits greatly from a kick of hoisin ($5.95).
