In a large pot over medium heat, saute the onion in the olive oil (or water) until soft and translucent.
1 Tablespoon extra virgin olive oil, ½ cup onions
Add the carrots, celery, and garlic, and saute for a few more minutes until softened.
½ cup carrots, ½ cup celery, 3 cloves garlic
Add the vegetable broth and bring to a boil. Add the orzo and white beans. Simmer, stirring occasionally, until the orzo is al dente.
4 cups vegetable broth, 6 ounces orzo, 1-15 ounce can white beans
Season with salt and pepper to taste. Remove from the heat and stir in the vegan pesto. Serve immediately with lemon wedges on the side.
salt and pepper, 3 Tablespoons vegan pesto sauce, lemon wedges
Notes
Store any leftover soup in an airtight container in the refrigerator for up to 3 days. Just keep in mind that the orzo will continue to absorb the broth as it sits. When you’re ready to reheat, simply add a splash of water or extra broth to loosen it up.For best results, this soup is not ideal for freezing. The pasta tends to get too soft after thawing.
