Break each leaf of lettuce in half. Cut the tomatoes into ¼-inch thick slices. Slice avocado into slices (you can use half the avocado or the whole avocado for extra).
Form burger patties into ¼-pound burgers that are about 5-inches in diameter. Salt and pepper each side.
In a large skillet, turn heat to medium-high heat and preheat the pan. Once the skillet is hot, place burger patties in the skillet.
Cook for about 4 minutes per side, flip and cook again on the second side. I like to cook my burgers to medium rare but cook to your liking. Remove from heat. If adding cheese slices, do so now, and allow to melt (trick is to cover with a lid here).

To assemble: Add two pieces of lettuce for the bottom, place the burger on top, then add the tomato, red onion, pickles, and avocado. Top with the additional two pieces of lettuce.
Serve immediately.
