Firstly, that's an impressive list of supported food mods.
This mod doesn't add in too much food so it shouldn't take too long to add support for.

SurvivalPlus: https://www.curseforge.com/minecraft/mc-mods/survivalplus

As the developer of this mod, I thought it'd be tidier if you add support for Survivalplus through your mod instead of vice versa. Thanks!
