These are basically McDougall's potato pancake recipe.
Very Very EZ

Potato Burgers
1/2 to 1 raw onion grated ( depending on your tolerance of Onions)
4 large Potatoes grated (peeling is optional wash well if you don't)
1/2 cup of whole wheat flour
1/4 cup of water

Mix all ingredients in a bowl. Using a non-stick pan on medium heat, or a
griddle at 325 degrees, ladle the mixture on pan and mash down until flat about
burger thickness. Cook for 8-10 minutes. Turn over and cook 5-8 minutes.

Hints:
Use a food processor to grate the potato and onion. The onion may get gooy but
that's o.k. Ore Ida has hash browns that are already grated, and I've been
meaning to try that as a time saver but haven't done it yet. If any one has
done this please post your success.
If you want to double this recipe, use separate bowls or it is too hard to mix,
I've already tried.
These freeze well.
I usually think of one potato as a serving. For two people the above recipe
could be dinner and lunch.
Top with all your favorite low fat condiments. It surprised us at how much
these taste like Real hamburgers with all the toppings.
