In a large pot over medium heat, saute the onion in the olive oil or a splash of water until soft and slightly translucent.
1 Tablespoon extra virgin olive oil, ½ cup onions
Add the carrots, celery, and garlic, and saute until soft.
½ cup carrots, ½ cup celery, 3 cloves garlic
Add the vegetable broth. Once it has come to a boil, add the pasta. Allow to simmer, stirring occasionally, until the pasta is cooked al dente.
4 cups vegetable broth, 6 ounces tiny pasta
Taste and add salt and pepper, as needed, then remove the soup from the heat, stir in the dill and lemon juice, and serve.
2 Tablespoons fresh dill, 1 Tablespoon fresh lemon juice, salt and pepper
Notes
Leftover soup can be refrigerated in an airtight container for up to 3 days. The cooked pasta will absorb the broth, so you may need to add a little water before reheating it. For best results, do not freeze this soup.
