Current idea is you throw the chicken on the ground and right click with salt, and smelt it to get cooked salted chicken, and you craft it with 2 bread and potato and carrot to form the chicken sandwich

Also a advancement called [tasty alchemy] (or something else)

Salt

• textures of salt
• way of getting salt
  • model
  • code

Extras:

• All the recipes
• The item for salted chicken
• The item for cooked salted chicken
• The ability to right click with salt at chicken
• The advancement

I ended up deciding against this to avoid confusion with the usage of salt in JEI
