Begin by mincing the garlic and finely chopping the fresh parsley. If using green onions, slice them thinly. Gather all your ingredients.

In a medium mixing bowl, combine the olive oil, red wine vinegar, and Creole mustard. Mix until emulsified.

Stir in minced garlic, chopped parsley, green onions, sugar, salt, black pepper, and cayenne pepper until well mixed.

Whisk vigorously until the mixture thickens or blend in a food processor for a smoother texture.

Toss your salad ingredients with the dressing. Let it soak for at least 20 minutes.

Transfer the marinated salad to a serving bowl and garnish with parsley or green onions before serving.
