Preparation: Preheat your grill or stovetop griddle to medium-high heat. In a large bowl, gently mix together 1 pound of ground beef with salt and pepper. Form the mixture into 4 equal-sized patties, making a small indentation in the center of each patty with your thumb to prevent puffing up during cooking.
Cooking the Patties: Place the patties on the preheated grill or griddle. Cook for 4-5 minutes on each side for medium-rare, or longer if you prefer them more well-done. During the last minute of cooking, you can place a slice of cheese on each patty if desired and close the lid to melt the cheese.
Toasting the Buns: While the patties are cooking, split the burger buns and lightly butter the cut sides. Place the buns, cut side down, on the grill or griddle until golden brown and toasted.
Assembling the Burgers: Spread condiments like ketchup, mustard, and mayonnaise on the bottom half of each toasted bun. Add lettuce, tomato slices, and pickles. Place the cooked beef patty on top, followed by additional toppings such as onions or avocado if desired. Cover with the top half of the bun and serve immediately.
