Marinated London Broil is a go-to staple on our healthy protein list. Warm or cold and thinly sliced, this flank steak special is a summer star.

One of our test kitchen cooks adapted this recipe from her family London Broil recipe. Instead of brown sugar or honey, we go with erythritol 'brown sugar.' The rest is the same. :) Make it the night before and flip the London Broil around lunchtime the next day so both sides are flavored. It broils up in a snap! Be careful not to overcook. London Broil should have a cool pink center, sliced thin.
