Carrots: Adds a touch of sweetness and a vibrant color to the soup.
Celery: Contributes a subtle bitterness and a crunchy texture.

Technique Tip for Making Vegan Split Pea Soup
To enhance the flavor of your split pea soup, consider adding a bay leaf during the cooking process. The bay leaf will infuse the soup with a subtle depth of flavor. Remember to remove it before serving. Additionally, for a creamier texture, use an immersion blender to partially blend the soup after cooking, leaving some vegetables intact for a hearty consistency.

Alternative Ingredients
split peas - Substitute with lentils: Lentils cook faster and have a similar texture, making them a good alternative in soups.
onion - Substitute with leeks: Leeks provide a milder flavor and can be used in the same quantity as onions.
garlic - Substitute with garlic powder: If fresh garlic is unavailable, garlic powder can provide a similar flavor. Use ¼ teaspoon of garlic powder per clove.
carrots - Substitute with parsnips: Parsnips have a slightly sweeter taste and similar texture, making them a good substitute for carrots.
celery - Substitute with fennel: Fennel has a similar crunch and adds a slight anise flavor, which can enhance the soup's taste.
dried thyme - Substitute with dried rosemary: Dried rosemary has a robust flavor that can complement the other herbs in the soup.
dried oregano - Substitute with dried basil: Dried basil offers a sweet and slightly peppery flavor, which can be a good alternative to oregano.

vegetable broth - Substitute with water with bouillon cubes: Bouillon cubes dissolved in water can replicate the flavor of vegetable broth.
salt - Substitute with soy sauce: Soy sauce can add a salty and umami flavor to the soup, but use it sparingly to avoid overpowering the dish.

How to Store or Freeze Your Vegan Split Pea Soup
Allow the split pea soup to cool completely before storing. This helps prevent condensation, which can lead to a watery texture.
Transfer the soup to airtight containers. For individual servings, use smaller containers to make reheating easier.
Label the containers with the date. This ensures you keep track of how long the soup has been stored.
Store the containers in the refrigerator if you plan to consume the soup within 3-4 days. The flavors will meld together beautifully over time.
For longer storage, place the containers in the freezer. The split pea soup can be frozen for up to 3 months without losing its rich, hearty flavor.
When ready to enjoy, thaw the soup in the refrigerator overnight if frozen. This gradual thawing helps maintain the soup's texture and flavor.
Reheat the soup on the stovetop over medium heat, stirring occasionally, until heated through. You can also use the microwave, heating in 1-minute intervals and stirring in between.
If the soup thickens too much during storage, add a splash of vegetable broth or water to reach your desired consistency.
Taste and adjust the seasoning with salt and pepper before serving. The flavors might need a little boost after being stored.
