All ingredients are of choice, use what you have / what you like. Easy for subs or sandwiches , everything is all in one place easier to make subs or sandwiches. One of our favorites to make other than the salad bar one. Can use multiple containers one for vegetables and one for meats. I ran out of room on this one there, i still had banana peppers, lettuce, baby spinach, to use but not enough to use another container. In this one pictured I used: mushrooms, red onions, cucumber, black olives, ham, and turkey, lunchmeat, pepperoni and salami, tomatoes, pepper jack cheese, and provolone cheese. Some compartments have two things in them: the meats and cheeses . This is a great option for on the go to take somewhere or even food prep . We like to pick out of throughout the week for lunches and restock as needed.
