Ingredients
1(10-ounce) bag curly-leaf spinach, rinsed
3/4 pound mustard greens, stemmed and rinsed
3 tablespoons unsalted butter (not needed - I just use a bit of veggie spray oil)
1 teaspoon cumin seeds
1 teaspoon ground coriander
1 teaspoon paprika
1/2 teaspoon ground cardamom
1/4 teaspoon ground cinnamon
1 onion, chopped fine
Salt and pepper
3 garlic cloves, minced
1 tablespoon grated fresh ginger
1 jalapeño chile, stemmed, seeded, and minced
1(14.5-ounce) can diced tomatoes, drained and chopped coarse
1/2 cup roasted cashews, chopped coarse
1 cup water
3 tablespoons chopped fresh cilantro (optional)
Preparation
Place spinach in large microwave-safe bowl, cover, and microwave until wilted, about 3 minutes. When cool enough to handle, chop enough spinach to measure 1/3 cup and set aside. Transfer remaining spinach to blender and wipe out bowl. Place mustard greens in now-empty bowl, cover, and microwave until wilted, about 4 minutes. When cool enough to handle, chop enough mustard greens to measure 1/3 cup and transfer to bowl with chopped spinach. Transfer remaining mustard greens to blender.
Meanwhile, heat oil in 12-inch skillet over medium-high heat. Add cumin seeds, coriander, paprika, cardamom, and cinnamon and cook until fragrant, about 30 seconds. Add onion and ¾ teaspoon salt; cook, stirring frequently, until softened, about 3 minutes. Add garlic, ginger, and jalapeño; cook, stirring frequently, until lightly browned and just beginning to stick to pan, 2 to 3 minutes. Stir in tomatoes and cook mixture until pan is dry and tomatoes are beginning to brown, 3 to 4 minutes. Remove skillet from heat.
Transfer half of onion mixture to blender with greens. Add half of cashews and water; process until smooth, about 1 minute. Return puree to skillet.
Return skillet to medium-high heat, stir in chopped greens and bring to simmer. Reduce heat to low, cover, and cook until flavors have blended, 5 minutes. Season with salt and pepper to taste. Transfer to serving dish, sprinkle with remaining cashews and cilantro, and serve.
