Lay the tortilla on a flat surface. Spread the egg salad over the center, leaving a small border around the edges. Top with the lettuce, if using. Fold in the sides and roll tightly, burrito-style.
Pack it for lunch:
Place the wrap inside a lunch container with fruit and veggies packed separately. Refrigerate until ready to place inside an insulated lunch bag with an ice pack.
Notes
Chilled egg salad is easier to roll into the wrap. Make it ahead of time and keep it in the fridge. Make the wrap in the morning.
Lettuce helps create a barrier between the filling and the tortilla and helps keep the tortilla fresh.
