Slow Cooker Spinach and Cauliflower Mac and Cheese

Grease or line the insert of a 6-quart slow cooker. Combine evaporated milk, stock, Worcestershire sauce, mustard, black pepper, garlic powder, and paprika in the slow cooker. Stir in processed cheese food and butter. Add macaroni and mozzarella cheese.

Cover slow cooker with the lid and cook on High, stirring every hour, until cheese is melted and macaroni is cooked, 2 to 3 hours.

Empty frozen spinach into a microwave-safe bowl and add 2 tablespoons water. Cover and cook in the microwave on high until hot all the way through, 5 to 7 minutes, stirring halfway through. Drain and press moisture from spinach. Add to macaroni and cheese in the slow cooker and stir.

Empty frozen cauliflower into a microwave-safe bowl and add 2 tablespoons water. Cover and cook in the microwave on high until hot all the way through, 5 to 7 minutes, stirring halfway through. Chop into smaller pieces if necessary. Add to macaroni and cheese in the slow cooker and stir.

Serve immediately or divide into freezer-safe containers for individual servings.
