Use a mixer on medium speed to beat the cream cheese until smooth. Add the cumin and Worcestershire sauce and mix. Add the shredded cheddar cheese, green onions, bacon, pecans, and jalapenos. Stir until well combined.
Shape the mixture into a ball (if the mixture is too soft to shape at this time, refrigerate for a couple hours).
Optional: To make the pumpkin shape, lightly flatten the top. Place the strips of American Singles cheese evenly around the outside of the ball, gently pressing the cheese into the ball so it is slightly indented. Press the stem from the bell pepper into the top to cover where the strips of cheese meet in the middle.
Cover and refrigerate for several hours, the longer the better to allow flavors to meld.
Serve with your favorite crackers or sliced veggies. We especially enjoyed it with pretzel chips and buttery crackers.
