Preheat oven to 350°F (175°C). Prepare a baking sheet by greasing it or lining it with parchment paper.
Roll out your crescent dough sheets and cut each one into 4 pieces, resulting in 8 pieces total.
Distribute the ham evenly among the 8 pieces of dough. Place a cheddar cheese stick on top of the ham on each piece. Fold in the ends of each piece and then roll to seal.
Place the prepared sticks on the prepared baking sheet.
In a small bowl, mix together melted butter, Worcestershire sauce, Dijon mustard, onion, and poppy seeds. Brush the butter mixture over each stick.
Place in the oven for 12-15 minutes or until they turn golden brown. Enjoy your Ham and Cheese Sticks hot and fresh from the oven!
Notes
For variation, try using different types of cheese or adding some herbs to the butter mixture.
