Spinach Salad Recipe -
1/2 cup salad oil
1/4 cup white wine vinegar
1/4 cup sliced red onion
1/2 teaspoon dried leaf basil
1/2 to 3/4 teaspoon salt
1/4 teaspoon ground black pepper
8 ounces thinly sliced fresh mushrooms
1 pound spinach leaves, torn into bite-size pieces
In a small bowl, combine oil, vinegar, onion, basil, salt, and pepper. Add mushrooms, cover, then let marinate for about 2 hours at room temperature or overnight in the refrigerator. Stir occasionally to keep mushrooms coated with marinade mixture.
Place spinach in a salad boil; add mushroom mixture and toss well. Serve immediately.
