Add oil to stockpot on MEDIUM. Add mirepoix and garlic; cook, stirring, 5-6 min, until soft but not browned.

Stir in lentils, tomatoes, stock, coriander, cumin, turmeric, cinnamon, and cayenne pepper. Cook, covered, 20-25 min.

Puree briefly (about 15 seconds) with handheld blender, just to thicken (don't puree all the lentils).

Stir in garbanzo beans and cilantro. Season to taste with salt. Simmer about 5 min on MEDIUM until heated through.
