Summer is the time of year when some of Lidia's favorite vegetables and fruits are at their best. Today, she shares some recipes that she loves making at home when entertaining, including corn and zucchini minestra; shrimp and mixed bean salad, a salad that is always part of the buffet table in Lidia's home; and lastly, polenta with honey and berries, a recipe Lidia has loved since she was a little girl.
