Anecdotal Story
I was hosting a game day party and wanted to make a fun and easy snack that everyone would enjoy. I had some leftover Italian sub ingredients, and the idea of these Italian Sub Squares came to mind. They were a huge hit! The combination of the warm, flaky crust, the melted cheese, and the savory meats and veggies was a winner. Now, they’re a regular at all my gatherings.
Ingredient Descriptions
- Refrigerated Crescent Roll Dough: This provides a convenient and flaky crust for the sub squares. You can find it in the refrigerated section of most grocery stores.
- Sliced Ham, Salami, Pepperoni: These classic Italian meats provide a savory and salty flavor to the filling. You can use your favorite combination of Italian meats.
- Sliced Provolone and Mozzarella Cheese: These cheeses add a creamy and melty texture to the filling. Provolone offers a slightly sharp flavor, while mozzarella is mild and milky.
- Roasted Red Peppers: Adds a sweet and smoky flavor to the filling. You can use store-bought roasted red peppers or roast your own.
- Banana Peppers (Optional): Adds a tangy and slightly spicy kick to the filling.
- Black Olives (Optional): Adds a salty and briny flavor to the filling.
- Eggs: Used to create an egg wash that gives the top crust a golden brown color and a shiny finish.

- Grated Parmesan Cheese: Adds a salty and nutty flavor to the top crust.
Equipment/Tools
