Quick Mother's Day Dinner: Shepherd's Pie

My finals/AP tests are coming up, so I am QUITE stressed and busy studying. Tomorrow is mother's day, so I am going to take a break from studying to make a special dinner for her. But I was thinking, my goodness, what can I make that is quick and easy and doesn't take up much time? So I came across this shepherd's pie recipe, and LOVED it :).

Here's the video: https://www.youtube.com/watch?v=mwiMEAxfCx8&feature=youtu.be

The good news is that it is naturally gluten-free, so you can make it with "regular" ingredients!
*Note that I didn't add wine to the recipe :)

Happy (Early) Mother's day!
