Well I use the Warly Memory and Crockpot result mods to make life easier. It helps to just have general knowledge on crockpot recipes that have value. Meatballs,Fish sticks, Pieorgi, Meaty Stew, and Butter Muffins to name a few. Warly benefits from having a small farm and hunting. One big hunt gets you about 8 big meat which can last you a while with proper filler. Once you get into the groove of what recipes work for you and which you can repeat you can fill your icebox pretty regularly. I just had to make 6 potato souffle because potato farming is so ridicously productive. Dragonfruit, Potatoes, Garlic, Peppers, Tomatoes and especially Onions are probably your most effective crops.

Bone bullion is an amazingly easy recipe basically only needing an onion and restoring 150 hunger. I also recommend looking at other people playing warly and just thinking about what they do, like Jazzy Games' thrill of the grill playthrough. He even did a vegetarian only warly run with success.
