Remove the wooden ends of the asparagus spears. Swirl a 1/2 teaspoon of olive oil in a skillet over medium heat. Add the asparagus spears in a single layer then cover with a lid and cook until the asparagus is bright green and still crisp, about 5 minutes. Uncover and season with sea salt and freshly cracked pepper, to taste. Continue to cook, stirring often until the spears are fork tender yet still a bit crisp, another 1-2 minutes.
