This just means your body’s lacking a specific nutrient found in meat. This is its way of telling you what it needs, by craving the flavor of the item its found in. It makes you crave the food which will cure this insufficiency.

I found myself craving fake meat recently. It’s the texture that’s so yummy. I also started making seitan recently to replace that texture/protein craving. Try it! Let me know if you want to know some good/easy ones.
