I do EE and I always go for beef in black bean sauce. It's always been my favourite, and so I couldn't believe it when I found out it's one of the lower synned chinese takeaways. I usually get it with boiled rice or vegetable noodles, which are both free.
Just remember that if you want prawn crackers, they are 1.5 syns for 2. The only problem with that is, if you're me, I can't keep away from them lol!! Enjoy your chinese xx
