Around here, the Amerikkkanized Chinese food places use "happy family" to refer to a mix of basically everything they have in the kitchen in a brown sauce. The specific ingredients vary by place, but it's usually
meat
at least beef, chicken, and shrimp, with slightly nicer places adding pork and/or scallops, maybe some imitation crab
with whatever veggies they have lying around. Carrots, bok choy, broccoli, mushrooms, cucumber, green beans, anything.
