Balsamic Mushrooms

This mushroom side-dish tastes just as good
at room temperature as it does hot from the stove,
so there's no need to worry if it's ready
to serve before the rest of the meal is done.

Ingredients:
1/4 cup olive oil
12 ounces white mushrooms, quartered
3 tablespoons balsamic vinegar
1 teaspoon coarse salt
1/4 teaspoon red-pepper flakes
Freshly ground pepper

Directions:
1.Heat oil in a skillet over medium-high heat.
Add mushrooms, and cook until golden brown.
Stir in vinegar, salt, and red-pepper flakes,
and season with pepper. Cook 1 minute more.
Transfer to a bowl, and serve.
