My hubby prefers his sandwiches with out eggplant, plainer... This is delicious too:
Roasted Red Pepper & Mozzarella Panini
Put it all together- Bread, peppers, mozzarella slices, basil leaves (I leave them whole) & finally the splashes of extra virgin olive oil & balsamic vinegar.
Close the assembled sandwich & cook it either on a panini maker OR on a grill pan with a weight up on the sandwich (another pan or heavy plate) until the mozzarella is melted.
