How to prepare solids for LO

Hi parents, How do you prepare solids food as dinner for your LO (my LO is 8.5mo now) if you gunna be out from 4-9pm. LO usually eats around 6.30pm or 7pm, will the food I prepare for him not fresh by then? Or is it okay to just skip solids for the day? I tried those ready to eat food pouch before but he doesn’t really fancy 😪
