A panini press is helpful, and it gives you those cool little ridges and valleys on the sides of your sandwich, but you can easily grill your sandwich other ways: • Electric Grill or Skillet - Set the grill to 275°-300°F (135°-150°C) and grill the sandwich low and slow; about 4-5 minutes on each side. Use a bacon/sandwich press or a small frying pan on top of the sandwich to press it down as it grills. • Waffle Iron - This is by far my favorite: it gives your sandwiches a funky waffle pattern as it presses it! • Grill Pan & Press - Heat up the grill pan and then use a bacon/sandwich press to press the sandwich from the top. Leave the press or pan on top while the sandwich grills. • Skillet & Press - Same using as a grill pan. • Double Frying Pan - Use a smaller frying pan on top of the sandwich to press it down as it grills in a large frying pan. If you just aren't into any of those ideas, just grill it as you would a grilled cheese sandwich.
