→ How can I make this dish spicier?
To add heat, incorporate diced jalapeños or a chopped hot pepper with the vegetables. You can also add red pepper flakes or a dash of hot sauce to the mixture while cooking. Another option is to include pepper jack cheese instead of or alongside the provolone. Serve with hot giardiniera or cherry peppers on the side for those who prefer extra spice.
→ Can I freeze leftovers of this dish?
Yes, the meat mixture freezes well without the buns. Allow it to cool completely, then store in airtight freezer containers or heavy-duty freezer bags for up to 3 months. Thaw overnight in the refrigerator and reheat in a skillet, adding a splash of beef broth if it seems dry. Fresh cheese can be added during reheating for the best texture.
