Prep the chicken: First, if your chicken breasts are thick, use a meat mallet to gently pound them until they’re about 1/2 inch thick. This ensures even cooking and helps them cook faster.

Season and bread: Set up your breading station with three shallow dishes. In the first dish, place the flour seasoned with a pinch of salt, pepper, garlic powder, and onion powder. In the second dish, beat the eggs and milk together. In the third, pour the breadcrumbs. Dredge each chicken breast in the flour, then dip into the egg mixture, and finally coat with breadcrumbs, pressing gently to adhere.

Pan-fry the chicken: Heat oil in a large skillet over medium heat. When hot, add the breaded chicken breasts and cook for 3–4 minutes per side or until golden brown. You want them crisp on the outside and cooked through on the inside. Use a thermometer to ensure the internal temperature reaches 165°F (74°C).

Top and bake: Once cooked, transfer the chicken to a baking sheet lined with parchment. Place a slice of deli turkey or chicken and a slice of Swiss cheese on each breast. Bake in a preheated oven at 375°F (190°C) for about 5–7 minutes, or until the cheese is fully melted and bubbly.

Serve immediately: Remove from the oven and let rest for a minute or two. Then serve hot alongside your favorite sides.
