Slow-Cooker Taco Ground Beef

Spray 5-quart slow cooker with cooking spray. Break up beef; place on bottom and up sides of slow cooker. In large bowl, mix onions, beans, salsa and taco seasoning mix; place in center of slow cooker over beef. Cover; cook on Low heat setting 8 hours. Drain beef mixture through strainer set over large bowl. Press with spatula or wooden spoon to break up any large chunks of beef. Divide into 4 portions. Use 1 portion immediately to fill tacos, dividing evenly among taco shells; top with cheese, then add favorite taco toppings. Transfer remaining portions to pint-size freezer containers, and freeze up to 3 months. Use one portion in your Mexican recipes that call for 1 lb ground beef cooked with taco seasoning mix. Just thaw overnight in refrigerator or defrost in microwave before using. Microwave in microwavable container 2 to 3 minutes on High or until steaming before adding to recipes that call for hot ground beef.
