Keep all the ingredients you need ready by cleaning and slicing the veggies and grating the cheese

Slice the bread loaf into half lengthwise

Layer the tuna into the base of the bread loaf followed by cheddar cheese slices

Add the remaining ingredients as toppings one after the other except the sauces and mozzarella

Wrap in aluminium foil if consuming later

Just before consumption, take off the sandwich from the foil and add the mozzarella cheese(optional)and microwave for 2-3 minutes

Add the sauces as desired

Serve hot with ketchup

Tip: it’s mostly variety of cheddar cheese /sometimes feta that subways make their sandwiches with. Hence mozzarella is an option. You can add other veggies/greens as per your choice
