1/2 cup chocolate chips
1/4 cup raisins, optional
2 teaspoons baking soda

In a very large mixing bowl, combine the eggs and sugars. Mix well. Add the salt, vanilla, peanut butter, and butter. Mix well. Stir in the chocolate candies, chocolate chips, raisins, if using, baking soda, and oatmeal. Drop by tablespoons 2 inches apart onto the prepared cookie sheets.
