Step 1

Add the olive oil to a large pot over medium heat. Once the oil is hot, add the onion, celery, and carrot. Cook, stirring occasionally, for about 7-9 minutes or until the onion is softened. Add the garlic, black pepper, and fresh herbs, and cook for another 2 minutes.

Step 2

Add the flour slowly while stirring the vegetables to coat them with it. Once all of the flour is added, cook for about 1 minute while constantly stirring. Very slowly add the white wine and vegetable broth, about 1/4 cup at a time, stirring continuously so that the liquid and flour are incorporated with no lumps.

Step 3

Stir in the potato, sweet potato, tomato paste, soy sauce, nutritional yeast, liquid smoke, and marmite. Bring to a gentle boil, then reduce to a simmer. Cook uncovered, stirring occasionally, until vegetables are tender and stew is thickened, 20-30 minutes.

Step 4

Stir in the frozen peas and red wine vinegar, and cook for another 5 minutes or until peas are warm. Season to taste with salt and pepper, and additional vinegar if desired. Serve hot.
