On your way to your usual taco1 stand, you notice a new place just opened, taking their menu to gloss over it later. But once you get back home from your adventures2, you notice the menu is incomplete! You curse and hex whatever compelled you to take that one menu instead of any other, but after calming down, you realize there might be a way to know what's missing...

What is the missing dish?
1: or any other nondescript junk food you enjoy
2: Anything can happen, anything
Hints:
As the name of the puzzle suggests, the food is only there for show, but the name of the food can also be the name of their color.
"The food contains additives and may show signs of resistance", this flavor text hints to two mechanics of the puzzle regarding the dishes and their color.
After getting a number for each dish, look at the story text, a hint towards what to do next is hiding in there...
