Million Dollar Cookies

Seriously, one of my mom’s favorite cookies!
1 cup margarine
1/2 cup white sugar
1/2 cup dark brown sugar
1 egg
1 teaspoon vanilla
2 cups flour
1/2 teaspoon salt
1/2 teaspoon baking soda
1/2 cup nuts

Beat sugar, butter, vanilla, and egg together until fluffy. Combine the dry ingredients and add to wet mix. Add nuts last. Form into walnut-size balls and roll in sugar. Place on a greased cookie sheet and with a fork, make two indentations that cross. Bake at 350 for 10 minutes.
