Pan-Roasted Sirloin with Salad of Arugula, Sweet Peppers, and Olives

Avoid using a salad spinner to wash and dry the arugula—the leaves bruise easily. Instead, dunk them in a sink of cool water and lift them into a colander. Pat dry with a kitchen towel. Simple salt and pepper will form a crust on the steaks when you sear them. I don’t normally serve anything else with this warm steak salad except the rest of the bottle of Cabernet used in the vinaigrette recipe.
