Jennifer Esposito, 28, an image consultant who lives in Rye Brook, N.Y., lived for four years with a man who ate only pizza, noodles with butter and the occasional baked potato. “It was really frustrating because he refused to try anything I made,” she said. They broke up. “Food is a huge part of life,” she said. “It’s something I want to be able to share.” A year ago Ms. Esposito met and married Michael Esposito, 51, who, like her, is an adventurous and omnivorous eater. Now, she said, she could not be happier. “A relationship is about giving and receiving, and he loves what I cook, and I love to cook for him,” she said.
