Heat oil in saucepan, add onion and celery and saute over medium heat for 10 minutes.
Add garlic until fragrant (careful not to burn), add frozen peas and stir. Set aside half a cup of stock, add the rest to the saucepan and bring to a slow boil for 5 minutes until peas are tender. Remove from heat, let it cool (ideally) and then add mint leaves.
Meanwhile, place cashews and half cup of reserved stock into blender and blend into a course mixture. Then add soup mixture and blend until creamy. Season with salt and pepper to taste.
Garnish with chives. Enjoy!
NOTES:If you forget to soak your cashews overnight, put them in boiling water for a half hour prior to using them in the recipe and drain.If you want texture in your soup, set aside 1 cup of peas and add them in once the soup is pureed.Caution: If you puree hot soup in a blender, BE CAREFUL not to burn yourself. Cover the small opening with a tea towel to allow steam to escape through the top.If you don’t have a high-power blender like a Vitamix, you can add all the ingredients to the saucepan and puree with an immersion blender.
