01 - Heat olive oil in a large pot over medium heat. Add diced onion, sliced carrots, and celery. Sauté for 5 minutes until vegetables begin to soften and become fragrant.
02 - Stir in minced garlic and diced tomato. Continue cooking for 2 minutes, stirring frequently to prevent garlic from burning, until tomato begins to break down.
03 - Add rinsed lentils, ground cumin, dried thyme, bay leaf, and smoked paprika to the pot. Pour in vegetable broth and stir well to combine all ingredients.
04 - Bring the mixture to a boil, then reduce heat to low. Cover and simmer for 20 minutes, until lentils are just tender but still hold their shape.
05 - Add egg noodles to the simmering soup. Cook uncovered for 8 to 10 minutes, stirring occasionally, until noodles are al dente and lentils are fully cooked.
06 - Remove and discard the bay leaf. Season with salt and black pepper to taste, adjusting flavors as needed.
07 - Ladle hot soup into serving bowls. Garnish with chopped fresh parsley and accompany with lemon wedges for squeezing over individual portions.
