How to Make It
Heat oil in a large saucepan over medium heat. Add onion; cook 12 minutes or until golden. Stir in ginger and next 4 ingredients (through garlic); cook 1 minute, stirring constantly. Add broth, lentils, and 1/2 cup water; bring to a boil. Cover, reduce heat, and simmer 25 minutes or until lentils are tender.
Remove from heat; let stand 5 minutes. Place half of lentil mixture in a blender. Remove center piece of blender lid (to allow steam to escape); secure blender lid on blender. Place a clean towel over opening in blender lid (to avoid splatters). Blend until smooth. Pour pureed mixture into a large bowl. Repeat procedure with remaining lentil mixture. Return pureed mixture to pan. Stir in milk and remaining ingredients; cook over medium heat 2 minutes.
