Velvet used to hate lunch. Before going to Beacon she didn't make many friends and usually sat alone at school, and on weekends her parents were usually to busy working to eat with her. For Velvet Lunch became associated with loneliness.
Even after she got into Beacon lunch was lonely. Because of a series of miss filled paperwork, rescheduling, an undead beowolf, and a time traveling monkey(Velvet's head still hurt whenever she thought of it) she had lunch a different period than her team. She spent her lunches alone except for when Cardin took time out of his oh so busy schedule to make her feel even more ashamed about herself than she already did.
Then she met Jaune. They had only been friends for a few days when he asked her to sit with him and his friends at lunch, and while she still didn't talk that much she felt great just being there. Jaune made lunch something to look forward to, something where she was surrounded by her friends and got to just enjoy the feeling of being with other people.
After her and Jaune got together lunch became even better. Lunch was the one time a day that the two of them were able be together everyday without having to worry about scheduling conflicts. They would talk, laugh, and even attempted to feed each other once(that event never happened again after the resulting food fight got them stuck detention for a week). Lunch became the time she got to spend with the man she loved, and she made sure to cherish every second of it.
After graduation and her separation from Jaune Velvet still did her best to make lunch something special. She would aways make sure she ate with at least one of her fellow hunters. Lunch became a time of bonding and making sure that their team was always on the same page.
When she got her job at Beacon she was always open to students coming in at lunch for extra help, and when she didn't have any students who needed help she would eat lunch with Jaune sharing stories about the rowdier kids in their classes. Eventually their daughter enrolled in Beacon and they would spend lunch watching over her making sure that nobody bothered her and her friends
Lunch used to a time that Velvet dreaded, but now it was one of the brightest points of her day.
