Drop minced garlic into the pot and cook for an additional minute until fragrant. Add tomato puree, chopped tomatoes, and drained chickpeas. Mix everything together.
Next, add in the dry orzo pasta and stir to mix it in.
Pour in the vegetable stock, then increase the heat and bring the mixture to a boil. Once boiling, reduce the heat to medium-low and let it simmer for 6-8 minutes.
Season to taste with salt and pepper. Let the soup simmer for 5 minutes more, allowing the flavors to meld together.
Ladle the flavorful Vegan Orzo Soup into bowls. Garnish with fresh herbs, a drizzle of olive oil, and a drizzle of vegan basil pesto, if desired. Serve warm with crusty bread for a comforting and satisfying meal!
