Prepare the Chicken: Pat the chicken tenders dry with a paper towel. Season with salt, pepper, and garlic powder.
Sauté the Chicken: Heat olive oil in a large skillet over medium heat. Add chicken tenders and cook for about 4-5 minutes per side until golden brown and cooked through. Remove and set aside.
Make the Glaze: In the same skillet, add apple cider, honey, soy sauce, Dijon mustard, apple cider vinegar, and cinnamon. Stir well and bring to a gentle simmer.
Add the Apples: Stir in the sliced apples and let them soften slightly, about 3-4 minutes.
Glaze the Chicken: Return the chicken to the pan, coating each tender with the apple-honey glaze. Let simmer for 3-5 minutes until the sauce thickens and fully coats the chicken.
Finish & Serve: Optionally, add a tablespoon of butter for extra richness. Garnish with fresh thyme or parsley and serve warm.
