Making Crack Burgers is a fun process. Follow these simple steps to ensure a mouthwatering result:

1. Preheat Grill or Skillet: Heat your grill or a skillet over medium-high heat. Brush lightly with olive oil.
2. Form Patties: In a bowl, season the ground beef with salt and pepper. Divide into four equal portions and shape them into patties. Make a slight indentation in the center of each patty.
3. Cook Onions: In a small pan, sauté the diced onions in olive oil until they are translucent and slightly caramelized, about 5-7 minutes. Set aside.
4. Grill Patties: Place the beef patties on the hot grill or skillet. Cook for about 4 minutes on one side, then flip over.
5. Add Cheese: After flipping, place a slice of cheese on each patty. Cook for another 3-4 minutes, or until the cheese is melted and the burger reaches your desired doneness.
6. Prepare Buns: While burgers are cooking, lightly toast the burger buns on the grill or in a toaster.
7. Mix Sauce: In a small bowl, combine mayonnaise, barbecue sauce, and Dijon mustard. Adjust seasoning as desired.
8. Assemble Burgers: On the bottom bun, spread a generous amount of the sauce mixture. Top with a cooked patty, followed by onions, lettuce, avocado slices, and tomatoes.
9. Finish and Serve: Add the top half of the bun to each burger. Let them rest for a couple of minutes before serving.

These steps make it easy to create Crack Burgers that are bursting with flavor and ideal for anyone craving a delicious meal.
