This Greek Sheet Pan Chicken and Potatoes with Quick Tzatziki is a flavor-packed, easy sheet pan meal, perfect for weeknight dinners or meal prepping! The chicken is marinated in a lemon garlic dill marinade, and then it gets roasted on a sheet pan with baby potatoes. I love to serve this meal with a pile of arugula, fresh mint, feta, red onion, cherry tomatoes, lemon, and a generous scoop of tzatziki!
