Preparation Steps

• Heat olive oil in a large pot over medium heat. Add the chopped onion and cook until softened, about 5 minutes.
• Add minced garlic and cook for another minute until fragrant.
• Add the tomatoes, vegetable broth, oregano, red pepper flakes (if using), salt, and pepper to the pot. Bring to a simmer.
• Cook for 20 minutes, or until the tomatoes have softened and the flavors have melded.
• Remove from heat and use an immersion blender to blend the soup until smooth, or carefully transfer to a regular blender.
• Stir in the crumbled feta cheese.
• Serve hot, garnished with fresh basil.
