Ginger dressing commonly found in Japanese restaurants is so tasty, I had to find the recipe.

Ingredients

1 celery stalk, chopped
1 clove garlic, chopped
1 small piece ginger root, chopped
2 tablespoons ketchup
2 tablespoons lemon juice
1/2 red onion, chopped
1/3 cup olive oil
1 tablespoon soy sauce
1/2 teaspoon sugar
1/3 cup rice wine vinegar
2 tablespoons water
1/2 teaspoon ground black pepper
1/2 teaspoon salt (optional)

Place all ingredients in a food processor and blend until smooth.
Serve on top of a green salad.
