Load up Creeper Woods and just slaughter every cow, sheep, and anything else that breathes. Getting all that delicious food you need. Which is 200 food items by the way. There is also an enchantment you can get on your armour that can spawn up to 3 food per use of your armour. It just occurred to me, a friend(s) with that same armour would speed things up a lot too! It takes 6 enchantment points to max out the skill. I wish you the best! -KC
As of June 27 2020 this trophy is extremely glitched. So a way you can get this to work. I had my friend try. And it worked on his second try.
Copy your save data to a usb or to the cloud. Then delete your save on your system. And delete your game and reinstall it. With a new character, playthrough the first couple of levels or until you get armour with the food items spawn every time you heal. And just keep doing that at your camp until your trophy/achievement pops. Or keep playing through Creeper Woods until your trophy/achievement pops. Until they patch it, this is the method that can potentially work.
Here is my video guide as a reference.
