  3. Add the cubed ham on top of the chicken.
Making the Cheese Sauce

  2. Once melted, sprinkle the flour on top and cook for 1-2 minutes until the mixture becomes dry and clumpy.

  4. Add the Dijon mustard, lemon juice, garlic powder, and salt. Simmer and whisk constantly for 3-5 minutes, or until the mixture thickens.
  5. Remove from heat and stir in the shredded Swiss cheese and grated Parmesan cheese. Taste and add more salt if needed.

Notes

This dish can be served on its own or over pasta or rice. For added flavor, consider incorporating herbs like thyme or parsley. For a crunchier topping, bake longer or use the broiler briefly at the end.
