Pre-sliced chicken breast can be cooked in a variety of ways, including baking, grilling, sautéing or frying, depending on the recipe or personal preference. To bake, preheat the oven to 375°F, season the chicken with salt, pepper, and any desired herbs or spices and place the slices in a lightly greased baking dish. Cook for 20-25 minutes, or until the internal temperature reaches 165°F. To grill, preheat the grill to medium-high heat, season the chicken with salt, pepper, and any desired herbs or spices and grill for 5-6 minutes per side, or until the internal temperature reaches 165°F. To sauté or fry, heat a few tablespoons of oil in a pan over medium-high heat, season the chicken with salt, pepper, and any desired herbs or spices and cook for 3-4 minutes per side, or until cooked through.
