With artisan goods being nerfed, speed-wise, cooking is currently a better way to deal with excess fish and insects. Grilled bugs and fish don't show up in the list of recipes, so I have to manually select one fish, click cook, play the mini-game, and then click some more. Doing this for 30 fish at a time is beyond grindy.
Please let me know if I'm missing something, as far as discovered recipes go. I didn't get all the cooking tools bought before the update, and now Luke's shop seems to be broken for buying the rest.
