Butterfly chicken is 3 syns
Spicy rice is 2.5
Macho peas aren't in the list, but calculator says 5.5
Most of the sauces are 0.5 per level tablespoon, but the sweeter ones are 1 syn (I don't use them, so not sure which they have in the restaurant)
Note that peas are only free, so you'd not have any superfree in that meal. I'd suggest swapping them for the mixed salad. Better balance for EE, and saving a nice chunk of syns.
