In a bowl, mix the ground beef, cooked macaroni, shredded cheddar cheese, crumbled bacon, salt, and pepper together until well blended.

Using your hands, form the mixture into burger patties aiming for even sizes.

Dip each onion ring first in flour, then in beaten eggs, and finally in breadcrumbs to coat.

In a large pan, heat oil over medium heat until shimmering.

Carefully add the breaded onion rings to the hot oil and fry until golden brown, about 3-4 minutes per side.

Once the onion rings are done, cook the burger patties in the same pan for 4-5 minutes on each side.

Assemble by placing a patty between two onion rings per serving. Serve warm.
