Begin by washing and trimming your vegetables. Dice the onion, celery, and carrots into bite-sized pieces, ensuring uniform sizes for even cooking. Set them aside.

In a large non-stick pot, heat 2 tablespoons of olive oil over medium-low heat. Once shimmering, add the diced onion, celery, and carrots. Sauté for about 7-10 minutes until softened and translucent.

Stir in 3 minced garlic cloves and your choice of dried herbs into the pot. Cook for an additional 1-2 minutes to release aromatic goodness.

Pour in 6 cups of water, bring to a gentle boil, then reduce heat to low to simmer for 10-15 minutes.

Use an immersion blender to achieve your preferred consistency, blending until slightly chunky or smooth. Taste and adjust seasoning with salt and pepper.

For added heartiness, stir in optional ingredients like cooked barley, rice, or beans. Simmer for an extra 5-10 minutes until tender.

Ladle the soup into bowls, garnishing with fresh herbs if desired. Serve hot with crusty bread or a fresh salad.
