Place thawed hamburger into a large mixing bowl.

Chop onion and jalapeno fine. (Make sure to wear gloves when chopping jalapeno to prevent burns.)

Chop cold butter into small squares.

Add onion, jalapeno, butter, cheese, salt, pepper, and garlic powder to hamburger mixture. Use your hands (with gloves!) to mix the ingredients into the hamburger.

Form 4-5 patties.

Grill until desired doneness, you can use a meat thermometer if you would like!

When hamburgers are fully cooked place Kraft Naturals Slices on top of each patty, close grill hood and allow the cheese to melt.

Serve on a bun with your favorite condiments.
