slice long ways down the entire bread and open it up

layer cheese on (I cut my slices in half and placed on each side of bread)

layer lettuce

layer ham

drizzle a bit of oil ( placing it in between meats will prevent from bread getting soggy)

layer salami

layer any other items you may want (red roasted peppers are great here)

close the bread

wrap in double saran wrap

place in fridge with a heavy weight on the top

when ready to leave, unwrap and re wrap with wax paper, slice up on the diagonal
