Instructions
Heat the oil in a large skillet over medium-high heat. Season the chicken with salt and black pepper and add to the hot pan. Sear until golden brown on both sides. Transfer the chicken to a plate and set aside.
Add the tomatoes to the pan and bring to a simmer, scraping up any browned bits from the bottom of the pan. Stir in the pesto and sour cream and return to a simmer.
Return the chicken to the pan (with any accumulated juices). Reduce the heat to medium-low and simmer for 5 to 7 minutes, until the chicken is cooked through (or longer for bone-in chicken and thicker cuts of chicken). Top with the parmesan cheese and green onions and red pepper flakes (if using) and serve.
