One 14.5-oz. can plain diced tomatoes can be substituted for the diced tomatoes with green chilies if less heat is desired.
Handling Hot Peppers:
Because hot chile peppers contain volatile oils that can burn your skin and eyes, avoid contact with chiles as much as possible. When working with chile peppers, wear plastic or rubber gloves. If your bare hands do touch the chile peppers, wash your hands well with soap and water.
For Easy Cleanup:
Line your slow cooker with a disposable slow cooker liner. Add ingredients as directed in recipe. Once your dish is finished cooking, spoon the food out of your slow cooker and simply dispose of the liner. Do not lift or transport the disposable liner with food inside.
