enough potatoes to fill a 9x13 baking dish (10- 12), peeled and sliced thin
1-2 onions sliced thin (optional)
1/4 cup olive oil margarine
3 T flour
2 cups vegetable or chicken broth
pepper to taste

Oil baking dish and layer potatoes (and onions), sprinkling each layer with pepper.

In a medium pot, melt margarine and add flour. Stir until bubbly, then slowly add broth, stirring continually until thickened.
