Heat a large skillet or grill pan over medium-high heat.

Add the bacon and cook for 4-6 minutes, or until golden brown and crispy. Leave any bacon grease that's left in the pan to cook your burgers in. Set bacon aside on a plate lined with a paper towel.

Meanwhile, in a large bowl, add the meat; Season with sea salt and pepper and stir well to combine. (If you love garlic, throw some minced garlic in there too.)

Using your clean hands, shape into 4 equal patties about 1/2 - inch thick.

In the same preheated skillet cook the burger patties for 3-5 minutes per side (for medium), or until they reach your desired doneness.

To assemble your burgers, use large lettuce leaves (I like to double up the lettuce leaves so they are sturdier) and spread with about 1 teaspoon each mayonnaise and ketchup. Top with your burger patty, 1 slice of crispy bacon, pickles, 1 slice of tomato, red onion or pickled onion, and a bit of mustard.

Wrap all the ingredients into the lettuce, pierce it with a large toothpick or a cocktail skewer to hold, and serve immediately!
