Cook the bacon until crispy, let it cool, and chop into bite-size pieces.
Assemble
Spread a thin layer of mayo or Ranch over the tortilla. Place lettuce in the center and layer with tomato, bacon, turkey, and cheese. Add mustard, if using.
Fold in the sides and roll tightly like a burrito.
Pack for Lunch
Place the wrap in a lunch container and refrigerate until ready to pack. Keep sides separate and pack inside an insulated lunch bag with an ice pack.
Notes
For a wrap that stays fresh longer and doesn't get soggy, keep the tomato toward the center with lettuce between it and the tortilla.
