Tip: For easy cleanup, try a slow-cooker liner. These heat-resistant, disposable liners fit neatly inside the insert and help prevent food from sticking to the bottom and sides of your slow cooker.
To make ahead: Stir in spinach (Step 3), cover and refrigerate for up to 3 days or freeze for up to 6 months. Stir in cilantro and lemon juice just before serving.
Equipment: 5- to 6-quart slow cooker
1 1/2 vegetable, 1 lean protein, 1/2 starch
