Season the chicken breast with salt, black pepper, and a pinch of dried oregano.
Heat the olive oil in a grill pan or skillet over medium-high heat.
Cook the chicken for approximately 6-7 minutes per side until the internal temperature reaches 165°F.
While the chicken is cooking, chop the romaine lettuce, dice the tomato, and slice the cucumber.
In a small bowl, whisk together the Greek yogurt and lemon juice to create a creamy dressing.
Place the cooked basmati rice in a serving bowl as the base.
Layer the chopped lettuce, tomatoes, and cucumbers over the rice.
Once the chicken has rested for 3 minutes, slice it into thin strips and place it on top of the vegetables.
Drizzle the lemon-yogurt dressing over the entire bowl and enjoy immediately.
