- 1 cup finely chopped yellow onions
- 1 cup finely chopped celery
- 1/2 cup seeded and finely chopped green bell peppers
- 2 teaspoons salt

Add the onions, celery, bell peppers, salt, and cayenne and cook, stirring, until the vegetables are softened, about 5 minutes. Add the garlic and cook, stirring, for 1 minute. Remove from the heat and stir in the parsley and green onions. Cool the mixture for 10 minutes.
