Slice the ¼ of a yellow onion in to thick slices and peel the garlic cloves.
Melt the vegan butter in a sauce pan on medium-high heat. Once melted, add the onion and garlic. Sauté for 2-3 minutes. Sprinkle the flour over and stir until no raw flour is visible.
Add in the fresh herbs and pour in the vegetable broth, soy sauce, and black pepper. Whisk together. Bring to a boil and then reduce to a simmer for 15-20 minutes or until slightly thickened.
Use a slotted spoon or strainer to remove the herbs, onion, and garlic.
Taste and season with addition black pepper and salt if needed.
Serve with mashed potatoes and vegan holiday roast.
