Prepare all ingredients as listed.

In a small bowl, mix ketchup, mayonnaise, and mustard until smooth to create the sauce.

In a bowl, combine ground beef, Worcestershire sauce, salt, and black pepper. Mix gently and form into patties.

Heat a skillet or grill pan over medium heat. Cook the patties, flipping once, until cooked through. During the final minute, place cheese on each patty and allow it to melt.

Toast the hamburger buns, cut side down, until lightly golden.

Assemble the cheeseburger by spreading the sauce on the buns. Layer with butter lettuce, tomato, the cheeseburger patty, and red onion, then close with the top bun.

In a glass or pitcher, combine sparkling water, lemon slices, and chia seeds. Stir well and allow the chia seeds to hydrate briefly, then stir again.

Serve the cheeseburger with carrots and hummus and lemon chia sparkling water.
