Meal Prep Sesame Chicken Breasts

1. Brush the chicken on both sides with the vinegar. Sprinkle the chicken on both sides with 1 teaspoon salt and a few grinds of pepper. Mix the white and black sesame seeds in a shallow dish. Firmly press the chicken into the sesame seeds until well coated on both sides.
2. Heat the olive oil and sesame oil in a large skillet over medium-high heat. Add the chicken and cook undisturbed until just starting to turn white, about 1 minute. Flip the chicken and cook undisturbed until the other side is turning white, about 1 minute. Reduce the heat to low, cover and cook until the chicken is completely cooked through and an instant-read thermometer inserted into thickest part registers 165 degrees F, about 10 minutes. Serve the chicken as a whole piece or sliced crosswise into strips.  
3. The chicken will keep up to 4 days. Let cool completely before refrigerating.
