Heat olive oil in a large pot over medium-high heat.
Add chopped onion and minced garlic. Sauté for about 5 minutes until the onion is translucent.
Stir in sliced carrots and diced potatoes. Cook for an additional 5 minutes.
Add green beans, peas, and diced bell pepper. Stir well to combine.
Pour in the vegetable broth. Add tomato paste, soy sauce, thyme, and rosemary. Mix thoroughly.
Increase heat to high and bring the stew to a boil. Once boiling, reduce heat to low.
Cover and simmer for 30-40 minutes, stirring occasionally, until vegetables are tender.
Season with salt and pepper to taste.
Remove from heat, garnish with fresh parsley, and serve warm.
