Mash the avocado and season with salt and pepper, if desired.
Assemble
Spread the mashed avocado over the tortilla. Top with spinach and ham, fold in the sides, and roll tightly burrito-style.
Pack for Lunch
Place the wrap in a lunch container with fruit and veggies packed separately. Refrigerate until ready to place inside an insulated lunch bag with an ice pack, if needed.
Notes
The avocado will eventually brown, but keeping it rolled inside the tortilla limits its exposure to air and slows the process. Guacamole can also be used in place of mashed avocado.
