Step 1

Pound chicken breasts to half-inch thickness.

Step 2

Heat oil in a large nonstick skillet over medium-high heat. Sprinkle chicken with one-fourth teaspoon salt and pepper and add to pan. Cook three minutes on each side or until done. Transfer chicken to a serving platter; keep warm.

Step 3

Add onions and mushrooms to pan; sauté for four minutes or until browned, stirring occasionally. Add garlic; sauté for one minute, stirring constantly. Stir in wine, scraping pan to loosen browned bits.

Step 4

Bring to a boil, and cook until liquid almost evaporates. Sprinkle mushroom mixture with remaining one-fourth teaspoon salt and potato starch; cook for 30 seconds, stirring frequently.

Step 5

Add soup to pan; bring to a boil. Cook two minutes or until slightly thickened. Remove pan from heat; add oil or margarine and thyme, stirring until incorporated.

Step 6

Serve over chicken.
