Most versalite and valuable product in my opinion.
Need hunger and Healing? 3 stone fruits + leafy meat and you got beefy greens for 75 hunger 40 hp. Basically Dragonpie which doesn't need your attention to grow ingridients
Need Sanity? Just 2 meats + 2 honey and you got jelly salad for 50! sanity That's dirt cheap sanity i'd say
Need everything? Veggie burger. Yeah you need to grow Onion, but just once, then wrap it and cook them every time you need it for 30hp 33 sanity and 37.5 hunger. Veggie Burger is the only thing that requires something from you but it's so strong it worth it
Need Hunger? Plant 20 fleshy bulbs and just eat cooked meat and even wolfgang will be satisfied for 3 seasons.
Leafy meat is op and i don't understand why it's so easy to get it in late game
edit:
Leafy meat removes your need to kill or farm something to get good healing/sanity dishes. Basically just removes one of most important game mechanics, that's why it's broken.
It was okay when there were no recipies for leafy meat because there is much food anyway
