Making your own Cheddar and Bacon Turkey Melt on Sourdough is uncomplicated when you follow these easy steps:

1. Prepare the Bread: Spread butter on one side of each slice of sourdough bread.
2. Assemble the Melt: On the unbuttered side, spread mayonnaise and Dijon mustard (if using) on two slices of bread.
3. Layer the Ingredients: Place sliced turkey breast on top of the mayonnaise layer, followed by crispy bacon, and then cheddar cheese.
4. Add Optional Veggies: If you like, add a layer of fresh spinach or lettuce and a slice or two of tomato.
5. Top the Melt: Place the other slices of bread on top, buttered side facing out.
6. Heat a Skillet: Preheat a skillet over medium heat.
7. Grill the Sandwich: Carefully place the sandwich in the skillet and cook for about 3-4 minutes, or until golden brown.
8. Flip Carefully: Gently flip the sandwich using a spatula and cook the other side for another 3-4 minutes until the cheese is melted.
9. Cheese Check: Ensure the cheese is fully melted and the bread is perfectly golden and crispy.
10. Cut and Serve: Remove the sandwich from the skillet, cut in half, and serve immediately.
