If it is more than a one off, I'm thinking it may be a random glitch from the last patch. There is a game algorithm that will force a Sim to cook at least several meals. It happens when one staffs a caterer by phone, at restaurants of course, doing specific meals. Or yeah, it's also at the Spice Festival when one or two designated Sims start grilling as the one pic shows. If Akira wasn't at the Spice Festival in the OP's case, maybe the algorithm latched onto him somehow. It's rather handy unless it gets out of control, haha.
