Ingredients:
2 6-oz cans Tuna OR 1 14 oz can Salmon - do not drain
1 1/2 cups flour
1 TBS garlic powder or minced garlic (optional)
2 eggs
grated parmesan cheese (optional)
Process tuna, garlic and eggs in food processor or blender (or mix in a
bowl). Add flour and mix to a brownie-like consistency. Spread into a 9x9-inch
greased pan. Bake at 350 degrees F for 20 minutes. When the brownies are
done, they will have a putty-like texture and the edges will pull away from
the sides of the pan.
Cut into squares and freeze.
