Prep all the ingredients like chop the onions and capsicum. Prep the cheese. Slice the bread loaf.
Brush some olive oil evenly all over on the bread slices.
Spread a light layer of pizza sauce. You need to spread the sauce only on one slice of the sandwich. Don't spread it on the second slice as this can make your sandwich soggy.
Place mozzarella cheese. If using a soft cheese, you can break it and if using processed cheese or a firm cheese, then grate and add.
Sprinkle some dried oregano. You can also add some fresh basil. Or you can opt to add your choice of herbs or Italian seasoning.
Now place chopped onions and capsicum. Do not stuff too much with the veggies or cheese. You can add veggies of your choice like steamed baby corn or sweet corn. You can also add sauteed mushrooms.
Cover with the remaining bread slices.
Place in a preheated sandwich maker or panini press. Do not press the top cover of the sandwich maker too much as then the cheese may spill outside after melting.
Grill till the sandwiches are crisp and golden. Grill or toast all sandwiches this way.
Serve pizza sandwich hot or warm with tomato ketchup. You can accompany some baked potato wedges or fries if you want with the grilled pizza sandwiches.
