Pat the lamb cubes dry on all sides with paper towels and season well with salt and pepper. In a large slope-sided sauté pan over medium-high heat, heat the oil until it shimmers. Distribute the meat evenly in the bottom of the pan without crowding it and don’t disturb it for several minutes. If you stir the cubes too soon, they will release water and the meat will boil instead of browning. After 3 or 4 minutes, turn the cubes over and brown them on the other side for another 3 or 4 minutes. Using a slotted spoon, transfer the meat to a bowl and return the pan to the heat.
