In large bowl mix all dry ingredients Flour, salt, cinnamon and baking powder. With mixer or wooden spoon mix wet ingredients together including sugar until well combined add cooled squash. Gradually ad flour mixture to wet ingredients until well combined I do all this with a wooden spoon so I don't break up squash but mixer will do. Last add the chopped pecans or what ever other nut you like. Fill your prepared muffin tins 2/3 of the way full.
