2Preheat your oven to 375°F (190°C).
In a large bowl, mix together the hamburger, diced onion, shredded cheese, and salt and pepper until well combined.
Form the mixture into small, bite-sized patties.
Wrap each patty with a slice of bacon, securing it with a toothpick if necessary.
Lightly dust each bacon-wrapped patty with flour, shaking off any excess.
Arrange the patties on a baking sheet lined with parchment paper.
Bake in the preheated oven for 20-25 minutes, or until the bacon is crispy and the patties are cooked through.
Remove from the oven and let them rest for a few minutes before serving.
