Heat a griddle or large cast-iron pan to medium heat and add 1 teaspoon of unsalted butter just to coat the bottom of the pan once it’s melted.
Add 2 slices of bread to the pan or griddle and cook for 2 to 3 minutes or just until browned.
Before flipping over the bread, add 1 more teaspoon of butter, then flip over the bread onto the melted butter and add a ¼ cup of cheese to each slice. Cook for 1 to 2 minutes or until the cheese starts to melt.
Spread 1 to 2 tablespoons of the sun-dried tomato mayonnaise on the top of each slice of bread with melted cheese.
Layer on one slice of the browned bread with cheese with mayo as follows: bacon, sliced chicken breasts, ham, and balsamic onions.
Next, place on the other slice of toasted cheese melted bread.
Cook the sandwich for another 1 to 2 minutes per side until it is golden brown all around. You may need to add another 1 to 2 teaspoons of unsalted butter to the pan or griddle to ensure the sandwich is well-browned.
Slice and serve the chicken melt with an additional side of sun-dried tomato mayo.
Notes
Make-Ahead: This chicken melt is meant to be eaten as soon as it’s done cooking. If you keep the mayonnaise, cooked bacon, ham, chicken, cheese, and balsamic onions separate, you can make this up to 2 days ahead of time.How to Store: It’s best to cover the mayonnaise, cooked bacon, ham, chicken, cheese, and balsamic onions separately. If it’s already assembled, cover it with plastic and keep it in the refrigerator for 3 days. This recipe will not freeze well.How to Reheat: Place the desired number of chicken melts on a sheet tray lined with parchment paper and bake them in the oven at 350° for 8 to 10 minutes or until warm. If you kept the main components of the dish separate, follow the procedures of the recipe for reheating.Texas toast is a great bread to use if you are not making it yourself.Feel free to use a non-stick skillet for making the sandwich as well.You may need to move the bread a little in the pan or the griddle to brown it evenly. If you want to keep this recipe very simple, cook the chicken breasts with salt and pepper, then just use regular mayonnaise.
