Preheat the oven to 180°C (356°F).
In a large skillet or non-stick pan, heat olive oil over medium-high heat.
1 tablespoon olive oil
Add the chopped onion, garlic, carrot, and celery to the pan and sauté for about 5 minutes, until slightly softened.
4 cloves garlic, 1 onion, 2 medium carrots, 2 ribs celery
Sprinkle in the flour and stir well to combine with the vegetables.
2 tablespoon plain white flour
Add the vegetable stock, potato, thyme, mixed herbs, soy sauce, salt and pepper. Stir to combine.
1 large medium potato, ½ teaspoon fresh thyme, 2 cups vegetable stock, 1 tablespoon soy sauce, ½ teaspoon mixed dry herbs, salt and pepper
Bring the mixture to a boil, then reduce the heat to a simmer. Let it cook for about 15 minutes, or until the potatoes and carrots are tender but not overcooked.
Remove from heat and set aside.
