Zucchini Mushroom Skillet

Halve the zucchini lengthways, then cut into 1-inch sections. Wipe the mushrooms clean with a damp cloth, then quarter them vertically. Halve the onion; and cut it into slices about 1/4 inch thick.

Heat the olive oil in a heavy skillet over medium-high heat. Add the zucchini, mushrooms, onion, and garlic, and stir-fry until the zucchini and mushrooms are just barely tender and the onion is tender-crisp (about 10 minutes).

Stir in the oregano, salt to taste, and serve.
