Lemongrass Beef over Rice Noodles (Bun Bo Xao)

This popular Vietnamese dish is wonderfully fragrant and tasty–best of all, it’s easy to make! The lemongrass adds great flavor to the beef and the generous use of fresh herbs and vegetables makes this dish so light and refreshing it’s often called a “salad”. If you’re short on time, buy frozen minced lemongrass at your local Asian grocery store. I also found it in a squeezable tube (like toothpaste) in the produce section of my grocery store. If you’re watching your carbs, omit the noodles and double up on the veggies. Yum! Making dinner just for two? This recipe is portioned for 2 servings or for one really hungry person. Enjoy!

1/2 pound beef flap meat or flank steak
