Greek Chicken Gyros are a delicious and satisfying meal that can be made at home. Start by marinating chicken breast strips in a mixture of Greek yogurt, lemon juice, garlic, oregano, salt, and pepper. Let the chicken marinate for at least 30 minutes. Heat some oil in a skillet, then add the marinated chicken and cook until browned and cooked through. In the meantime, warm pita bread in the oven or on a stovetop griddle. To assemble the gyros, spread tzatziki sauce on the pita bread, then add the cooked chicken, sliced tomatoes, sliced cucumbers, and sliced red onions. Roll up the pita bread and enjoy!
