In a 4- to 6-quart slow cooker, combine the beef, potatoes, tomatoes (and their juices), onion, apricots, cumin, ginger, cinnamon, cayenne, 3/4 teaspoon salt, and 1/2 cup water.
Cook, covered, until the meat is tender, on high for 4 to 5 hours, or on low for 7 to 8 hours.
Ten minutes before serving, prepare the couscous according to the package directions.
Add the chickpeas to the slow cooker and cook until heated through, 2 to 3 minutes. Stir in the spinach. Serve with the couscous and sprinkle with the almonds.
To freeze:Omit the couscous and spinach. Cool the beef to room temperature and divide among freezer containers or bags. Freeze for up to 3 months.
To reheat:Thaw in a bowl of cold water or overnight in the refrigerator. Cook in a pot, covered, stirring occasionally, until heated through, 20 to 30 minutes. Stir in the spinach. Serve with the cooked couscous.
