Season Chicken: Place chicken breasts in a baking dish. Pour about 2 tablespoons olive oil over each one and use your hands to rub down and ensure they are fully covered. Season with salt, pepper and any Greek seasoning (if using).
Add Other Ingredients: Place tomatoes, artichoke hearts, olives, potatoes and garlic cloves around the chicken. Drizzle those with a bit more olive oil and just a sprinkle of salt and Greek seasoning (if using).
Bake: Move the whole pan to the preheated oven to bake for 30-40 minutes or until chicken has an internal temp of 165 degrees F (use meat thermometer). If chicken has not reached an internal temp of 165, continue cooking for 5-10 minute increments until fully cooked.
Serve: Enjoy immediately.
Notes
Potatoes: Be sure to use smaller potatoes, so they cook through in the timeframe given. If you only have large russet potatoes, make sure to cut them down into very small chunks!
Storage: leftovers can be kept in an airtight container in the fridge for 4-5 days.
