From Whole Foods weekly newsletter; this dish will freeze well. Serves 4. In Kenya, this dish is called sukuma wiki, named after the dark, leafy greens from which it's made. The name translates roughly to "push the week," implying the ingredient's stellar ability to stretch meals, making them last to the end of the week. Throughout the country, the popular dish is eaten without utensils, with chapati (a variety of flatbread) or ugali (a type of cornmeal mush) used to scoop up bites instead.

Heat oil in a large pot over medium heat. Add onion and jalapeño (if using) and cook, stirring often, until softened and golden brown, 7 to 8 minutes. Add tomatoes and cook until collapsed and juicy, about 10 minutes more.

Add kale, water, lemon juice, salt and pepper, toss once or twice, cover and simmer, stirring occasionally, until kale is tender and flavors have come together, 10 to 15 minutes. Spoon into bowls and serve
