Put ground beef in a mixing bowl and add the garlic powder, italian seasoning, and salt and pepper. Mix it up with your hands and shape into 2 patties. Set aside.
Chop up the jalapenos and onions into small strips. Remove the jalapeno seeds if you aren't into a little heat.
In a small pan, heat the olive oil on medium. Toss the onions and jalapeno strips in and sauté. Keep these cooking until the edges start to burn just a little. This gives the jalapenos a nice crunch.
Heat a large grill pan over medium high heat. Add the patties to cook. Flip after 5 minutes, then finish cooking until cooked through to your desired pink-ness
