Egg Free Dairy Free Simple Shepherd's Pie

My family loves Shepherd's Pie and this is such an easy and fast way of making it.

Simple Shepherd's Pie

1 lb cooked ground beef or any meat desired
1 can beef gravy (I use Campbells)
1 can mixed vegetables or any desired
3-4 cups prepared mashed potatoes (to make it fast, I use Betty Crocker Mashed Potato Buds)

Combine the ground beef, gravy and vegetables. Transfer the mixture into an 8x11 or 9x9 baking dish. Spread the mashed potatoes evenly over the top. Bake at 350 for 15-20 minutes or until heated through.
