There is no pumpkin in the recipe: the inside is savory smooth cheddar, cream cheese and spices. Great to eat right away and even better when made ahead!
In a medium bowl, mix all of the ingredients until well blended and smooth. Form the cheese mixture into a ball. Wrap in plastic and chill until firm.
Pour nuts onto a plate and roll the ball in the nuts until completely covered. Using your fingers or the handle of a wooden spoon, start at nearest side and create 8 indentations around the cheese ball to resemble pumpkin sections. When done, push down on the top to flatten the cheese ball slightly.
Break a three inch section off one end of the pretzel rod. Stick the broken section into the top of the cheese ball to create a pumpkin stem. Press pistachio nuts into the top of the cheese ball around the pretzel stem. Cover in plastic and chill until serving.
Note - original cream cheese and regular sharp cheddar cheese were used for this recipe. Reduced fat cream cheese can be substituted for regular. Fat-free cream cheese is not recommended because it doesn't bind well with the other ingredients.
