Preheat a large work or saute pan with 1 teaspoon oil to high, then saute half of the chicken at a time until all the pieces are almost cooked through (opaque), then add half of the garlic and cook for another 30 seconds or so.
When the first batch is done, set it aside on a large baking sheet or platter and repeat the process with the other half of the chicken and garlic (with another teaspoon of oil).
White meat should take 3 to 4 minutes per batch to cook through, dark meat 5 to 6 minutes.
