Directions:
Heat a skillet to medium heat. Add butter and oil, then the sliced onions.
Cook 10 minutes, then add sugar, balsamic vinegar, and salt. Continue cooking 10–12 minutes until deep golden and caramelized.
Heat a cast-iron skillet or flat top over medium-high heat.
Divide ground beef into 4 loose balls (do not compact tightly).
