When you're in the mood for lo mein, you can always get takeout, but here's a supereasy recipe that actually takes less time to prepare than you'd spend waiting for your order. For the beef, sirloin tips are idea, but you can also make this dish with flank steak.
Stir the spaghetti into a pot of lightly salted boiling water and cook it according to the package directions. Drain the noodles well, then return them to the pot and toss them with the sesame oil.
Heat the vegetable oil in a large nonstick skillet over medium-high heat. Add the broccoli and onion and cook, stirring often, for 3 minutes. Add the ginger and garlic and continue stirring while the mixture cooks for another 30 seconds. Add the sirloin and cook it, stirring often, for 5 minutes or until it is no longer pink.
In a small bowl, mix the broth, soy sauce, brown sugar, and oyster sauce. Add the soy sauce mixture and the pasta to the skillet and continue cooking, stirring often, for 1 to 2 minutes or until everything is heated through. Serve the lo mein hot. Makes 4 to 6 servings.
