Step 1
Start by bringing a pot of salted water to a boil. Toss in the egg noodles and cook them until they’re tender but still have a bit of bite—about 5 minutes should do it. While the noodles cook, heat a large skillet over medium-high heat. Add the ground beef, mushrooms, onion, garlic, mustard powder, salt, and pepper. Cook everything together, stirring now and then, until the beef is browned and the veggies have softened, about 7 to 10 minutes. Drain off any extra fat or liquid from the pan.
