OKLAHOMA CITY - The principal at Harding Charter Preparatory High School said 130 percent more students are buying the school lunches than they did last year.
So what's changed?
A new food service company took over the cafeteria this year.
Keystone Food Service is new to the public school lunch scene.
They got their start serving food at fraternities and sororities and are now expanding to schools.
Their philosophy is a little unique.
"It's not the easiest way and it's not the most inexpensive way but we feel it's the best way," Josh Sanders said with Keystone Food Service.
All of their food is made from scratch.
"We control everything that goes into that, salt, fat, no preservatives; it's just healthier, it's better," he said.
Justin Hunt is the principal at Harding Charter Prep.
He said most students wouldn't eat the cafeteria lunch before this year.
"In the past, they were using vending machines, eating bags of chips," Hunt said.
He said the student complaints were pouring in.
Harding junior Ofei Wellington said he had to force himself to eat the lunches last year.
He said, "You would have to ask them like, 'what's this?' It's all like these are green beans. It's like, they're brown," Wellington said.
Wednesday's lunch menu is grilled buffalo chicken sandwiches and home-made sweet potato fries.
Every day a salad bar is available with fresh fruit and vegetables, included with the lunch.
"They're a lot more adventurous than we thought," Jesse Feeback said with Keystone Food Service. "They eat tons more fruit and vegetables than I could ever imagine."
Feeback actually grilled the chicken for the day's lunch on a grill just outside the school.
The cooks are constantly trying new recipes.
"Last week we had a chicken bruschetta pasta dish that went over well, we tried new," Sanders said.
Keystone currently contracts with six schools, three of which are charter schools in the metro area.
They're looking to expand into even more schools.
