The other night I made my own mashed potato pie and my kids LOVED it. I decided to post my recipe on my cooking blog for those looking for an easy meal to make that kids will like (well my kids did). This recipe probably has most ingredients that are already in your freezer/pantry.
Below is the link to my mashed potato pie recipe:
