Ingredients

Instructions

  1. Step 1: Slice 1/2 medium red onion into thin rings. In a small bowl, combine 1/4 cup white vinegar, 1/4 cup water, and 1 tbsp sugar. Stir until sugar dissolves, then add the sliced onions. Let sit for 15 minutes to pickle.
  2. Step 2: Meanwhile, divide 8 oz ground beef into two equal portions and form into patties about 3/4 inch thick. Season both sides with 1/2 tsp salt and 1/4 tsp black pepper.
  3. Step 3: Heat 1 tbsp olive oil in a skillet over medium-high heat. Add the patties and cook for 4 minutes on one side until nicely seared, then flip and cook another 3-4 minutes for medium doneness.
  4. Step 4: While the patties cook, toast 2 burger buns in a toaster or on a dry pan until golden brown, about 1-2 minutes.
  5. Step 5: Spread 1 tbsp mayonnaise on each bun bottom. Top with 1 cup mixed greens, the cooked burger patty, and a generous portion of the pickled red onions (about half the jarred onions per burger). Crown with the top bun and serve immediately.
