Egg foo yong is a most approachable, Cantonese-style dish with a tradition of its own: an eggy pancake with a kitchen-sink helping of tender and crisp vegetables, pork, shrimp, even water chestnuts and bean sprouts.

Egg Foo Yong With Greens and Onion (Serves 2) 

Serve with fried rice.
Choy sum is a leafy Asian green whose crisp, slim stems work well here. If you can't find it at the supermarket, use the stems of broccolini, or peeled broccoli stems, instead.

1 small red or white onion
110g choy sum (see headnote)
3 large eggs
1 chicken bouillon cube
Large pinch sugar
Large pinch kosher salt
2 teaspoons vegetable oil

Peel the onion and cut it in half, then into very thin half-moon slices. 
Coarsely chop the choy sum stems, to yield at least 2 cups. 
Reserve the leaves for another use, if desired.
Whisk the eggs lightly in a medium bowl. 
Crush enough of the bouillon cube to yield 1/2 teaspoon, then add it to the bowl, along with the sugar and salt, whisking to incorporate.
Heat the oil in a medium non-stick skillet over medium heat. Once the oil shimmers, add the onion and stir to coat. Cook for about 5 minutes, stirring once or twice, until softened.
Distribute the choy sum evenly over the onion; cook for about 3 minutes, then gently pour in the egg mixture, tilting the pan so the egg runs evenly around the vegetables. Use a wooden spatula to stir the eggs once around the pan, then cook for 2 or 3 minutes, undisturbed, until browned on the bottom and the edges are set.
Use the spatula to cut the egg foo yong in half, then turn each half over. Cook for a minute or two, until lightly browned on the second side. 
Divide between individual plates; serve right away.
