Preheat the oven to 350°F (175°C).
In a medium bowl, mix the cooked ground beef, dried minced onion, dill relish, and Thousand Island dressing until well combined.
Unroll the crescent sheets onto a cutting board or parchment paper.
Place 6 slices of cheese on each crescent dough rectangle.
Divide the meat mixture evenly between the two dough sheets.
Roll up each crescent dough starting from the short side, then slice the ends off and cut each roll into 6 pieces.
Arrange the pinwheels on a parchment-lined baking sheet (you may need two sheets).
Sprinkle sesame seeds on top for that iconic Big Mac touch.
Bake for 12-15 minutes or until golden brown and delicious.
Let them rest for about 5 minutes, then serve with extra Thousand Island dressing for dipping.
