How to Make It
Combine first 7 ingredients (through avocado) in a blender; add 1/4 teaspoon salt. Process until smooth; stir in 1/8 teaspoon salt and chopped fresh cilantro. Cover and chill 2 hours.
Preheat oven to 400°.
Lightly coat tortillas with cooking spray. Combine remaining 1/8 teaspoon salt, cumin, and 1/8 teaspoon chile powder in a small bowl; sprinkle cumin mixture over tortillas, tossing gently to coat. Arrange tortillas in a single layer on a baking sheet. Bake at 400° for 5 minutes or until crisp. Cool in pan. Place 1 cup soup in each of 4 bowls; top evenly with tortilla strips.
