Things went better．The local food bank started to provide her with some free vegetables every month．Her son finally had enough to eat．Once he told Lisa that the dishes she made were delicious．Suddenly，an idea came to Lisa's mind，"Why not share my recipes（食谱）on the Internet？"She did．Many people liked her recipes and she became popular．
