“Come on Over!” — which is released May 4 — is Heiskell’s fourth cookbook. “We can finally have people over!” Heiskell exclaimed. “I hope this book inspires people to have friends over. If we learned anything during the past year, it’s how important friends and family are.” Like her previous three cookbooks, “Come on Over!” is full of Southern recipes that are easy to prepare, but full of flavor and Heiskell’s Southern flair. The recipes are tried-and-true dishes that she has used for years in her home as well as for affairs catered by her Elizabeth Heiskell Catering catering company.
