Prepare and chop or dice leek, onion, carrot, turnip, swede and zucchini into small bite size pieces.
Heat a stock pot on low heat and add 2-3 tablespoons of cooking oil. If oil free add small amount of water to saute' vegetables.
Add leek, onion, carrot, turnip, swede and zucchini, saute' while stirring for a couple of minutes until vegetables begin to sweat down.
Add Italian herbs, turmeric and chilli powder continue to sauté and stir another couple of minutes.
Add vegetable broth or water and stock cubes, turn heat up to high, once it comes to a boil turn heat down to a gentle simmer and cook until vegetables are just tender.
While vegetables are cooking take a saucepan and heat up enough water to cook the pasta shells.
Once water has come to a boil add a 1/2 teaspoon of salt add pasta shells and cook until al dente, drain pasta and set aside.
When vegetables are tender add drained cooked pasta shells, tomato paste, crushed or diced cooked tomatoes, beans and nutritional yeast flakes.
Continue cooking for another ten minutes to combine the flavours.
If you want more liquid in your soup now is the time to add it. Sometimes I add another 2 cups of water and another stock cube.
Taste for flavour add more seasoning etc if needed. Add sweetener now if you choose to, it brings all the flavours together.
Finally add fresh parsley stir in and leave.
