Preheat your oven to 375°F (190°C) and prepare a 9x13-inch baking dish with non-stick spray.

Unroll one can of refrigerated crescent rolls and lay it flat in the prepared baking dish, pinching seams to create a solid base.

Layer deli roast beef evenly over the crescent roll base, then sprinkle with Swiss cheese.

In a mixing bowl, combine dry onion soup mix, melted butter, Worcestershire sauce, and garlic powder. Mix well and drizzle over the cheese layer.

Place the second can of crescent rolls on top, pinch seams to seal. Bake for 15-20 minutes until golden brown.

While baking, warm beef broth in a small pot over medium heat until simmering.

Allow the squares to cool for 5-10 minutes, then slice and serve with the warm beef broth for dipping.
