Let’s dive into the process, step-by-step, so you can create these mouthwatering squares with ease. Cooking should be as joyful as sharing a meal with loved ones, and I’m here to guide you through each step.

1. Preheat your oven to 375°F (190°C). Lightly grease a 9×13-inch baking dish or line it with parchment paper.
2. Unroll one can of crescent roll dough and press it into the bottom of the prepared dish, sealing the seams to create a single layer.
3. Layer the roast beef over the dough, followed by the slices of provolone cheese.
4. In a small bowl, mix together the mayonnaise, Worcestershire sauce, Dijon mustard, onion powder, and garlic powder. Spread this mixture evenly over the cheese layer.
5. Unroll the second can of crescent roll dough and place it over the top, again sealing the seams.
6. In another small bowl, combine the melted butter with the dried rosemary. Brush this mixture over the top layer of dough.
7. Bake in the preheated oven for 25-30 minutes, or until the top is golden brown and the cheese is bubbly.
8. While the squares are baking, heat the beef broth in a small saucepan over medium heat until warm but not boiling. Season with salt and pepper to taste.
9. Remove the dish from the oven and let it cool slightly before slicing into squares. Serve with a small cup of the warm beef broth for dipping.

Remember, as my abuela always said, “Cocinar con el corazón” — cook with your heart. Let your senses guide you, and enjoy the process!
