Bacon Cheeseburger Bites

Based on the recipe found here.

BACON CHEESEBURGER BITES

1 Tbsp. extra virgin olive oil

1 Tbsp. butter

1 small sweet onion, chopped

6 slices center-cut bacon

3/4 lbs. lean ground beef

1 Tbsp. Worcestershire sauce

1/2 tsp. salt

1/2 tsp. pepper

1/4 tsp. garlic powder

cheese, sliced

1. Heat olive oil and butter in a large skillet over medium heat. Add onions then sprinkle with salt and cook, stirring occasionally, until dark golden brown and tender, about 20 minutes. Scoop onto a plate to cool slightly then set skillet aside to be used again in a bit.
2. Meanwhile, cook bacon in oven. Lay bacon strips on foil-lined baking sheet. Place in cold oven. Turn oven to 400 degrees (bacon will cook as oven heats up.) Cook for 20 minutes. Chop each strip into quarters once cool enough to handle then set aside.
3. Combine ground beef, Worcestershire sauce, salt, pepper, garlic powder, and slightly cooled caramelized onions to a large bowl then mix. Roll into large meatballs then flatten out and place onto a foil-lined baking sheet. Bake for 8-10 minutes or until cooked through. If your ground beef has a higher fat content make the burgers a bit larger to compensate for the loss of size while fat renders out during baking.
4. You can quickly fry the burgers if you want them a bit browned. Or put them under the broiler. Stack with bacon and cheese and skewer with toothpick for easy eating.
5. Can add roasted jalapeño or poblano pepper, guacamole and top with half a cherry tomato like the original recipe calls for.
