Beef Burgers

In a large mixing bowl, gently combine ground beef, salt, pepper, garlic powder, and onion powder. Don't overmix - this keeps the burgers tender. Divide the mixture into 4 equal portions and gently form into patties about 3/4-inch thick. Make a small indent in the center of each patty with your thumb to prevent puffing during cooking. Place patties on a plate and refrigerate while preparing toppings.

Preheat grill to medium-high heat or heat a large skillet over medium-high heat with vegetable oil. Cook the patties for 3-4 minutes on the first side without pressing down - this keeps the juices in. Flip and cook for another 3-4 minutes for medium doneness (internal temperature of 160°F). In the last minute of cooking, place cheese slices on top of each patty to melt. Remove from heat and let rest for 2 minutes.

While burgers rest, lightly toast the hamburger buns on the grill or in a toaster until golden. Spread mayonnaise on the bottom bun, add lettuce leaf, then place the cooked patty with melted cheese. Top with tomato slices, red onion, ketchup, and mustard as desired. Crown with the top bun and serve immediately while hot. Serve with your favorite sides like fries, onion rings, or coleslaw.
