Instructions
Gently combine all ingredients in a large bowl. Use your hands to mix. Don't overmix; this makes tough meatballs. Mix just until everything is evenly combined.
Use a tablespoon or your hands to form the mixture into 1.5-inch meatballs. Make them all about the same size for even cooking in the slow cooker.
Add meatballs to slow cooker. Add 1 cup of beef broth or gravy.
Cook on low for 4-6 hours (for 1.5 inch meatballs), or 6-8 hours for larger meatballs. Check internal temperature with a meat thermometer; it should reach 160°F.
Make gravy (see recipe in article).
Serve meatballs with gravy and your favorite sides.
