In your slow cooker combine crackers, cereal, pretzels and pecans. Stir.

Now in a bowl combine your butter, worcestershire sauce, salt, garlic powder and onion powder. Stir.

Pour this butter mixture over the stuff in the slow cooker.

Toss to coat it well. I just use a big wooden spoon. Try not to be too rough though.

DO NOT COVER THE SLOW COOKER!!!

Now turn your UNCOVERED slow cooker on high for 2 hours. Stir every 30 minutes or so.

Now turn it down and cook UNCOVERED for another 2 to 4 hours on low. I found 2 hours sufficient. Stir every 30 minutes.

Let cool.

Store in an airtight container.

Try not to eat all the pretzels while they are piping hot.
