Brown the meat and drain well. Add onion and garlic to the pan and toss until translucent.
Add browned meat, onion and garlic to a slow cooker and add remaining ingredients along with just enough water to leave the mixture well-moistened.
Turn the slow cooker to low heat and cover. Allow to cook for 4-6 hours, stirring occasionally and adding water only if necessary to avoid sticking or scorching.
