• 4-1/2 cups unseasoned mashed potatoes
• 1 cup matzah meal
• 1/2 cup potato starch
• 3 eggs, beaten
• 2 tablespoons oil
• 1 teaspoons salt
• 1/8 teaspoons pepper
• Additional matzah meal as needed

Tuna Filling:

• 3 cans tuna - standard size
• 1 onion, diced
• 1 teaspoons garlic powder
• 1/4 cup slice mushrooms
• 1 egg, slightly beaten
• 1/2 teaspoons salt
• 1/4 teaspoons pepper

Combine mashed potatoes, matzah meal, starch, eggs, oil and seasonings. Mix well and form into a soft dough. Using 1/4 cup of dough for each, form into 24 patties. Coat both sides with matzah meal. Place 12 patties on greased cookie sheet. Flatten and spread out dough slightly with your fingers.

Spread 1/3 cup of tuna filling in centre of each dough round. Top with remaining pastry. Pinch together and bake 15 minutes or longer until brown.
