Step 1

Dry-fry crushed red pepper flakes in a large saucepan until they start to jump around the pan and release their aroma, about 1 minute. Add oil, carrots, and lentils; stir to combine. Add water and crumbled bouillon and bring to the boil. Reduce heat, cover, and simmer until lentils have swollen and softened, about 15 minutes.

Step 2

Blend soup to desired consistency (smooth or chunky) with an immersion blender or food processor. Stir in milk and cumin. Ladle soup into bowls and sprinkle with toasted sunflower seeds.
