This one was a bit modifed from a recipe I found online and I am calling it a vegan shepard's pie as that is the ebst way for me to describe it.
Ingredients:
2 packages polenta from TJ's
6 cups of veggie broth
1 chopped red onion
1 bag frozen corn
1 bag froen spinach
1 bag frozen brocolli
3 baked sweet potatoes
2 TBsp tahini
2 tsp ginger
1 package silken tofu

Directions:
Bring the veggie stock to a boil and then add the corn and onions.
Chop of the polenta in to small slices and add to the broth. Cook on low for 40 minutes, stirring frequently.
Add the spinach and pour in to a casserole dish.
Stick pour broccoli pieces on to the top and push down in to the mixture.
Blenderize the sweet potatoes, tahini, tofu, and ginger.
Pour on top of the casserole dish. Bake at 300 for 20 minutes.
This was a good one to serve with bread and as leftovers.
