Season chicken with salt and black pepper.
Heat Olio Taibi Nocellara Extra Virgin Olive Oil in a large wide skillet over medium-high heat.
Add chicken pieces to hot oil in a single layer, do not crowd pan, you will likely not fit all pieces in at one time. Cook chicken for about a minute on each side, until lightly brown. Remove to a plate. Repeat process until all chicken is cooked.
In same pan, lower heat to medium, add garlic, capers, and red pepper flake. Sauté for about minute, do not let garlic get too much color.
Add tomatoes and any juices along with chopped fresh oregano, raise heat back to medium-high, scrape pan to loosen any brown bits.
Simmer sauce for about 5-10 minutes, until thickened.
Add chicken back into the pan with sauce, simmer gently for a couple minutes to warm the chicken through.
Serve warm with additional fresh sprigs of oregano over pasta or with bread for mopping up the sauce with.
