Ground turkey
Green beans
Spaghetti sauce, or any type of tomato sauce. Just enough to color mashed potatoes.

Brown turkey burger. Put in sauce. Place burger in the bottom of a pie pan, add green beans on top and then top all this with the mashed potatoes. Bake at 350 for about 30 minutes. Should be thick enough to cut like a pie.

Could use deerburger or lean hamburger.
