Prepare all of your veggies, spices and set aside.
Add 6 cups of water to a large pot and bring to a boil, add the bouillon cubes, salt, pepper and nutritional yeast, and whisk to dissolve. Alternatively, you can use 6 cups of vegetable stock instead of bouillon cubes.
Immediately add all of the veggies (carrots, celery, onion, garlic and potatoes). You are adding all of the ingredients except the pasta. Stir well and bring back to a boil. Once boiling, immediately turn to the lowest heat, cover and simmer around 10 minutes until the carrots and potatoes are becoming tender, but not fully.
Add the pasta and bring back to a boil over medium-high heat. Once boiling, leave the lid off and cook for about 10 minutes, or until the pasta is tender, but still firm. Taste and add any more salt, if needed.
Add plant protein. If you’re using a vegan chicken recipe, simply add the chunks of “meat” to the soup after they’ve been steamed (but without the marinade). If you’re using dehydrated soy chunks, add them to the soup without soaking them first, and let them soak up the broth before serving the soup.
Garnish with freshly chopped parsley and a fresh squeeze of lemon juice right before serving.
