In a small bowl, stir together the mayonnaise and barbecue sauce until fully blended. Set aside.

Toss the peppers and onion with olive oil, salt, and black pepper.

Grill or sauté over medium-high heat for 8 to 10 minutes until tender and lightly charred. Set aside.

Preheat a grill or skillet/griddle over medium-high heat.

Season the burger patties lightly with salt and black pepper.

Cook the patties until browned and cooked to your preferred doneness, turning once or as needed. Cook time may vary depending on patty thickness, cooking method, and whether cooking from frozen.

During the last 1 to 2 minutes of cooking, top each patty with a slice of cheddar cheese.

Avoid pressing down on the patties while they cook, as this can squeeze out flavorful juices.

Lightly toast the potato buns until warm and lightly crisp. Toasting helps the buns hold up better and adds texture.

Let the patties rest for 3 to 5 minutes.

Spread the BBQ mayo on the toasted buns.

Assemble the burgers with the patty on the bottom bun, then top with the grilled peppers and onions. Add the top bun and serve right away.
