1️⃣ Form the Patties:
Divide the ground beef into three equal portions and shape into patties slightly larger than the rye bread slices.

2️⃣ Season the Patties:
Season both sides of each patty with onion powder, garlic powder, salt, and pepper to taste.

3️⃣ Cook the Patties:
Heat a large skillet over medium-high heat. Cook the patties for 4-5 minutes per side until browned and cooked through. Set aside.

4️⃣ Prepare the Secret Sauce:
In a small bowl, mix together mayonnaise, chopped turkey bacon, ketchup, sugar, and relish. Stir until smooth and set aside.

5️⃣ Butter the Bread:
Spread softened butter on one side of each rye bread slice.

6️⃣ Assemble the Patty Melts:
Place three slices of buttered bread (buttered side down) in a skillet. Layer each with:

Two slices of provolone cheese

A cooked beef patty

Two slices of cheddar cheese

Spread secret sauce on the non-buttered side of the remaining three bread slices and place them on top of the sandwiches, sauce-side down.

7️⃣ Toast the Patty Melts:
Cook over medium heat for 3-4 minutes, until the bottom bread is golden brown and the provolone cheese has started to melt.

8️⃣ Flip and Finish Cooking:
Carefully flip the sandwiches and cook for another 3-4 minutes until the cheddar cheese melts and the bread is golden and crispy.

9️⃣ Serve:
Allow the patty melts to cool slightly before slicing them in half. Serve with extra secret sauce on the side for dipping.
