Cook the bacon in a large nonstick skillet over medium-high heat until crisp. Remove bacon from pan, reserving 2 teaspoons drippings in pan. Crumble bacon; set aside. Add broccolini and leeks to the drippings in pan; sauté 4 minutes. Add oregano, pepper, and garlic, and sauté 3 minutes. Stir in remaining ingredients, and cook 30 seconds or until liquid almost evaporates. Sprinkle with the crumbled bacon.
