Prepare Ingredients:

1. Cook and slice or shred the chicken breast.
2. Slice the avocado and remove the pit.
3. Dice the tomatoes.
4. Shred the lettuce, if needed.

Warm Tortillas:

1. Place the flour tortillas on a microwave-safe plate and microwave them for about 10-15 seconds to warm them up. This will make them more pliable and easier to roll.

Assemble Wraps:

1. Lay the warm tortillas flat on a clean surface.
2. Add a layer of shredded lettuce on each tortilla, leaving some space at the edges.
3. Place the cooked chicken slices or shredded chicken on top of the lettuce.
4. Arrange the avocado slices on top of the chicken.
5. Sprinkle diced tomatoes and shredded cheddar cheese over the avocado.

Season and Dress:

1. Season the filling with salt and pepper to taste.
2. Drizzle ranch dressing (or your preferred dressing) over the filling ingredients.

Wrap Up:

1. Fold the sides of the tortilla over the filling, then tightly roll the tortilla into a wrap, starting from the bottom edge.

Serve:

1. Place the wraps seam-side down on a serving plate.
2. If desired, slice each wrap in half diagonally before serving.
