Prepare the ingredients as listed above so everything is ready to use.
Mix the ingredients for the sauce until fully combined. Set aside.
In a bowl, mix the ground beef with black pepper, paprika and garlic powder until combined well.
Portion the ground beef into two thin patties per portion and shape into patties slightly larger than the buns.
Heat a grill pan or skillet over medium-high heat. Cook the patties for 2–3 minutes on the first side, then flip and cook for 1 minute longer.
Toast the buns cut-side down in the skillet until golden.
Assemble the burgers: Spread sauce onto the bottom bun, then layer with the burger patties, drizzle with more sauce and top with pickle and tomato. Place the top bun on.
Combine the ingredients for the sparkling water. Stir and let sit 2 - 3 minutes for the chia to bloom.
Serve the burgers with carrots, hummus, and lemon chia sparkling water.
