Potato and Rice Burgers

Sauce:
1 cup plain non fat yogurt
1 tbs fresh lemon juice
1/4 tsp. soy sauce
1/8 tsp crushed red pepper
1/2 tsp. ground cumin
1 clove garlic, minced
2 tbs chopped fresh parsley

Burgers:
1 large potato, peeled and diced
1 cup cooked brown rice
1/4 cup dry whole wheat bread crumbs
1/2 onion minced
1 to 2 tsp. tamari or soy sauce
2 tbs chopped parsley

In a bowl, combine sauce ingredients. Place in refrigerator to chill.
Prepare grill or griddle. Boil potato in water over medium heat until
tender, about 10 min. Meanwhile, combine remaining ingredients in a medium
bowl. Drain potato and mash with a fork or masher. Add potato to bowl, mix
well and form into 4 thin patties. If potato mixture is too dry to hold
together, add a little water before making patties. Grill patties 4 to 5
min. on each side until lightly browned. Serve on hamburger buns with sauce
and your choice of fixings.

I don't have a grill so I broiled mine instead and they turned out great!
Brown and crispy! These have a nice taste.
