Place the ground beef, water, Worcestershire sauce, chopped garlic, sea salt, and pepper in a large mixing bowl. Using your hands, knead the ground beef with the ingredients until fully incorporated.
Divide the ground meat into four even mounds. If you would like smaller burgers, divide the patties into six even mounds.
Using your hands, mold each mount into a patty. Set each patty onto a clean plate.
Heat two tbsp of vegetable oil in a large skillet. Add each patty and cook the patties on medium to high heat for 5 minutes. When brown on one side, flip the patties over with a spatula and cook for another 5 minutes. Cook the patties for an extra minute if you would like the meat to be medium to well done. As you cook, do not push down on the patty with the spatula---this will make your hamburgers less juicy.
When each patty is ready, turn off the heat and add a slice of cheese on top if desired. Allow the cheese to melt.
Serve each hamburger on a hamburger bun with a slice of lettuce and tomato and a squeeze of ketchup and mayonnaise.
