Preheat oven to 180°C –
Chop off the bottom 1/5 of the asparagus and discard – chop the remaining length of stalk into 3 and put the tips in one Pyrex oven dish, and the rest into another Pyrex dish.
Drizzle some olive oil on both lots, and toss to coat evenly with the oil.
Roast the tips for between 10 and 15 minutes until they are starting to brown, but do the rest of the stalk for around 5 minutes longer. They are tougher and will require a little more roasting. When sufficiently roasted – just enough to soften and bring out the flavour – remove from oven and set aside.
Heat a large saucepan or pot on a medium heat. Add around a Tbsp oil and add in the red/yellow diced onion, garlic and celery. Cook for 5 minutes or so until translucent and browning slightly.
Add peas, vegetable stock/(water & stock cube), plant milks and pepper & nutritional yeast.
Return to boil and add asparagus shortly after.
Simmer for around 7 minutes – until peas are tender. Remove from heat.
Add lemon juice, then use a stick blender to thoroughly blend the soup.
Best eaten with toast or garlic croutons.
