Ingredients and substitutions for vegan cauliflower soup

How to make vegan cauliflower soup
Firstly, preheat the oven to 350 degrees F/180 degrees C and line a large baking tray with parchment paper. To the baking tray, add the cauliflower, onion, garlic, olive oil, onion powder, cumin, salt and pepper. Stir to combine, making sure all the vegetables are well-coated in the seasoning. Bake in the preheated oven for 20 minutes.
When ready, transfer the roasted vegetables to a blender or food processor, but save some of the cauliflower for garnishing. Add plant based milk, nutritional yeast, lemon juice, vegetable stock, salt and pepper. Blend until smooth.
Pour the soup into serving bowls, and add equal amounts of green peas to each one. Serve garnished with extra roasted cauliflower.
