Peel carrots & chop off the ends. Slice into rounds. Cut celery into large chunks and chop the onion. Put chopped veggies in a large mixing bowl and toss with dry spices (cumin, paprika, garlic powder, onion powder, & black pepper).
Spread veggies onto a baking sheet and roast for 30 minutes.
Place roasted veggies in to a high powered blender and add coconut milk, vegetable broth, and red chili paste. Blend until smooth.
