A Gourmet and Ecchi series from 2017 worth adding to your list.
The Moon Festival is Tootsuki Academy's annual gourmet gala, where students compete against each other to earn the most profit through selling their cuisine of choice. But for Souma Yukihira, it is also his first opportunity to challenge the Elite Ten, the supreme council that rules over the academy. However, this is only the beginning of Souma's war against the Elite Ten; a nefarious plot is underway that will provide Souma with the challenge he desires but will also shake the very foundations of Tootsuki Academy itself.
