Beef and broccoli seems to be a standard 'Chinese' dish everywhere but China. In almost 30 years of eating in China, I have never seen it on a menu anywhere. Or in family kitchens.
S: 西兰花; T: 西蘭花 (xī lán huā, literally western orchid), western broccoli is a relatively recent introduction, although now China is the top producer.
The people selling 'ingredients for dishes' have two sets involving broccoli. Neither are 🐮 牛肉 (niú ròu), beef.
1) 🐔 S: 鸡肉炒西兰花; T: 雞肉西蘭花 (jī ròu chǎo xī lán huā), stir fried chicken and broccoli.
For 10.90元 / $1.52, a 200 gram chicken breast and 250g broccoli will be delivered to the door.
2) S: 虾子炒西兰花; T: 蝦子炒西蘭花 (xiā zǐ chǎo xī lán huā), stir fried shrimp and broccoli.
13.90元 / $1.93 and you'll get 150g of shrimp and 200g broccoli.
I've never eaten these combinations. There are many green vegetables I'd rather eat than broccoli.
