- 1 medium sweet potato, peeled

- 1 tbsp toasted sesame seeds (for garnish)

Add beef slices to the marinade, stir to coat, and let sit while you prep the vegetables.

Cut sweet potato and onion into 0.5-inch-thick half-moons. Thread beef strips (accordion-folded) and vegetable pieces alternately onto skewers.
- 4
Heat 2 tbsp oil in a large skillet over medium-high until shimmering, about 90 seconds.

Working in batches, lay skewers flat and sear 3–4 minutes per side without moving. Edges should char and brown deeply.
