There's A Party In My Tummy!

Do you like cooking? I sure do. I have a problem though, I'm not open to trying new foods most of the time. I detest seafood, the mere sight of fish is gross to me. I would have to say pork is my favorite, just because our cuisine is very versatile with the way we tend to prepare it. All of which are delicious. After pork, I'd say meat and chicken are runner ups. So I was making a Meat Pie, as I'll call it (pictured above). I had made ground beef with veggies and decided I'll mash some potatoes up and put them over the meat (sort of the American version of Shepherd's Pie) and topped it with some cheese. 

I did this in a small aluminum pan just to see if it would turn out good, and it did. It was really tasty. Sad part is i ate half and left the other half in the microwave for the next day. I come home to re-heat it and its gone. Now, no one confesses but I know it didn't walk out the door! lol. I'm looking forward to making it again in a bigger portion. 

★Does anyone have any advice on how to make it a little more moist?★
★Would love some ideas!★
