Can I make a REALLY SIMPLE shepherds pie with these ingredients?

Cook your ground beef, preferrably with onion, salt and pepper (season salt if you have it works great). Drain and put in a cerole dish with your vegetables. I prefer a thicker stew-type, so mix 1 T cornstarch with your broth and pour over top. Top with mashed potatoes. You can put your stuffing in, but I'd save it for another day. If you have cheese, you can sprinkle cheese on top. Bake at 350 until it's nice and bubbly.
