Cook the center-cut bacon in a cold skillet over medium heat until the fat renders and the bacon is crispy, then drain on a wire rack.
Season the chicken breast with salt and garlic powder, then grill or pan-sear until the internal temperature reaches 165 degrees Fahrenheit.
In a small vessel, whisk the Greek yogurt and Dijon mustard until emulsified to create a high-protein spread.
Lay the whole wheat tortilla flat on a clean work surface.
Apply the Greek yogurt mixture evenly across the center of the tortilla.
Arrange the romaine lettuce and tomato slices in a linear fashion over the spread.
Place the sliced grilled chicken and the crispy bacon strips on top of the vegetables.
Fold the left and right edges of the tortilla inward by one inch.
Roll the tortilla tightly from the bottom edge to the top to encapsulate the ingredients.
Slice the wrap at a 45-degree angle and serve.
