Smoky Avocado & Mushroom Drinkable Soup

For the Soup, place all ingredients in blender; cover. Blend on high speed until smooth. Remove insert from blender cover. With blender on, gradually add enough water [1 to 1 1/2 cups (250-375 mL)] until soup is a drinkable consistency.

For the Topping, heat oil in medium nonstick skillet on medium heat. Add remaining ingredients; cook 5 to 7 minutes or until mushrooms begin to brown and pistachios are toasted, stirring occasionally.

Pour soup into beverage glasses. Top each with 1 tbsp (15 mL) of the Topping.

TIP: Make Ahead: Prepare soup and topping as directed. Cover and refrigerate up to 3 days. To warm soup and topping, place in microwavable mug. Microwave on HIGH for 30 seconds to 1 minute or until heated through.
