I made a makeover of the wonderful sesame chicken recipe here on Spark. My version doesn't add any sugar (just uses some honey) and throws in chili flakes and teriyaki sauce to give it more that general tsao's feel. recipes.sparkpeople.com/recipe-detail.asp?
Lot of chicken and a large serving size so its 340 calories and 46g protein. Then just serve it over some stir fry veggies and maybe some rice.
But yeah, the traditional buffet way of frying chicken, covering it in flour and sugar, frying again, then coating in a sugary sauce can really pack on the useless calories
