Recipe - Green Bean Casserole in the Crock Pot

I found this recipe while searching the Internet for something to do with my harvest of green beans that came on rather quickly once the weather began to cool off from the 90s.  I made a few minor adjustments because, as always, I didn't have all of the ingredients that it called for in the pantry.  Here is the link to the original and below is what I used.  It turned out rather good.

My Ingredients:

1/2 cup shredded Mexican 4-Cheese
1 cup French-fried onions

Preparation
1. Wash and trim green beans and place in the cooker.

3. Toss the beans gently to coat.

5. Add the French-fried onions.
6. Cover and cook on low for 4.5 hours.
