Cauliflower and Potato Sabzi with Spices

Separate cauliflower into florets to measure 4 cups, reserving stems. Cut stems into thin slices to measure 1 cup. Heat 1 1/2 tablespoons oil in a Dutch oven over medium-high heat. Add potatoes, cumin seeds, and garlic; stir-fry for 6 minutes or until potatoes are crisp-tender. Stir in water and next 5 ingredients (water through pepper). Add the cauliflower florets and stems, stirring well; cover, reduce heat, and simmer 20 minutes or until vegetables are tender. Uncover, and drizzle with 1 1/2 teaspoons oil, cilantro, and Garam Masala, tossing well.
