When Vince Gill and Amy Grant married in 2000, their union brought together not just two gifted singers, but also two families: Vince's daughter Jennifer, and Amy's children, Matt, Millie and Sarah. Rachael asks Vince if he has any tips on how to make a happy, blended family.

"Time," Vince says. "Time was really the key ingredient for me. I knew that Amy's kids, at the time we got married, I knew they probably weren't crazy about me, but I told Amy just give them time. I'm not trying to be the super human that's coming in to save everyone's life. They'll find me in their own way and in their own time, and they all have. Time was a great healer for everybody."

Rachael and Vince head into the kitchen to make Sausage, Pepper & Onion Burgers. Vince says, "Elvis always thought that the hamburger was the perfect meal. It had all four of the major food groups: meat, bread, vegetables and mayonniase."

"Oh, no mayonnaise for me!" Rachael says.
