Yam Shepherd's Pie

I was going to use these yams to make soup, but I've been making a lot of soup lately and I'm a little tired of it. This is easier and sticks to your ribs a little more. :)

Yam Shepherd's Pie--$7.13

2 lbs. yams, cooked and mashed ($2.40) or 1 can ($3.55)

1 lb. ground beef ($2.99)

1 onion ($.74)

1 lb. frozen mixed vegetables ($1)

Brown the ground beef in a large skillet. Once it's browned, remove to a small casserole dish, leaving some of the grease in the pan. Add the onions and vegetables to the skillet and heat, stirring periodically, until the vegetables are heated through and the onions start to brown. Add to the casserole and mix with the meat. Spoon the potatoes evenly over the top and sprinkle with salt and pepper. Heat the pie under a broiler until it is a little crisp and browned on the top.
