Dayton Independent School Board Chairwoman Rosann Sharon knows the importance of students trying new foods. She was inspired to do the same when kale chips were served earlier this school year.“I’ve never been a big kale eater. In fact, I don’t know that I had even ever had kale,” Sharon said. “I looked at it and I thought, ‘OK, we want the kids to try things, so I should try some, too.’”She liked it so much she went back for more, and later bought some to make at home.Sharon, who taught math at Dayton High School for 32 years before retiring in 2008, is in her seventh year on the school board. She began volunteering at Lincoln Elementary four years ago.“When I was still teaching, we kept saying, ‘Can’t you have a soup and salad bar that you can get?’”
