Stir in the minced garlic, diced carrots, and celery. Cook for another 5 minutes until the vegetables begin to soften.
Add the dried thyme, oregano, and red pepper flakes (if using) to the pot. Stir well to combine and cook for 1 minute until fragrant.
Pour in the vegetable broth and bring the mixture to a boil. Once boiling, add the orzo pasta and cook according to package instructions, usually about 8-10 minutes.
When the orzo is al dente, stir in the chickpeas and chopped spinach. Cook for an additional 2-3 minutes until the spinach is wilted.
Remove the pot from heat and stir in the lemon juice. Season with salt and pepper to taste.
Serve hot, garnished with fresh parsley.
Notes
For a heartier soup, add diced potatoes or zucchini along with the carrots and celery.
Substitute quinoa for orzo for a gluten-free option, adjusting cooking time as needed.
