Spread mayonnaise and mustard on each of the sub halves.
Top the mayonnaise side with lettuce, oven roasted turkey, cheese slices, and tomato slices. Close the sandwich with the top half of the sub bread.
Serve it with fresh fruit and veggies if desired.
If making this sub for later, place the cheese between the bread and the tomato so the top half of the sub sandwich doesn’t get soggy. Refrigerate until ready to pack inside a lunch bag, with or without an ice pack.
Notes
Turkey pairs great with cheddar, Swiss, Cheddar, and your favorite sliced cheese.
