Hawaiian Yam Bake

8 large sweet potatoes or yams peeled and cut into 2 inch chunks
2 cups pineapple chunks
1 cup banana; sliced
2 cups hearts of palm; cut into 2 inch chunks
2 cups tempeh; cut into 1 inch chunks
2 cups dried lentils
3 cups vegetable stock
1/2 cup honey
1/2 cup cider vinegar

Preheat oven to 250F.

Combine all ingredients in a large roasting pan or casserole dish.

For a sweeter taste, use apple juice to replace 1/2 of the vegetable stock.
