Burger:

1. Preheat your grill or skillet to medium-high heat.
2. Weigh your portion of ground beef and shape it into a 3 oz ball.
3. Place the ball in the pan.
4. Using a heavy spatula, smash the patty into the pan and scrape the patty to the edges of the pan. It should be so thin that you should be able to see through it.
5. Season patty with salt and pepper.
6. When the patty develops a crust, use the back side of the spatula to run under the patty and pull it apart from the pan.
7. Cook for 3-4 minutes per side or until it reaches your desired level of doneness. During the last minute of cooking, add a slice of cheese to the patty and let it melt.

Burger Sauce:

1. In a small bowl combine all ingredients. Use a whisk to mix thoroughly.

Assembly:

1. Toast buns.
2. Spread the sauce on the bottom half of each bun.
3. Add a patty with melted cheese on top.
4. Finish with the top half of the bun.
