Step 1

Heat the oil, then add the vegetables. In a 12-inch skillet over medium heat, heat the olive oil until it begins to shimmer.Add the vegetables in a single layer. It's fine if the vegetables overlap, but try not to crowd the pan too much; cook in two batches if you're using a smaller skillet. Sprinkle the salt evenly over top.

Step 2

Stir-fry the vegetables until they have some light brown spots, about 5 minutes.

Step 3

Add the water or other liquid and cover the skillet. Let the vegetables steam, covered, just until tender. This usually takes about 4 minutes.

Step 4

Check the vegetables. Uncover the pan and use a fork to spear a few of the vegetables and see if they're tender or still crunchy. If done, cook the vegetables, uncovered, just another minute or so to let any remaining liquid evaporate from the pan. If not done, add another tablespoon or two of liquid, cover, and steam a bit longer

Step 5

Serve: When the vegetables are tender, transfer them to a serving dish. Sprinkle with parsley (optional) and serve while still warm.
