WOAH! A whole chicken leg?
I hope you at least mean leg as in leg and thigh.
Don't skimp on the chicken man, buy a whole chicken.
If you're only cooking for one then look for a small chicken or at least 1/2 or 1/4'd.
My little lady makes the best damn chicken soup I've ever had and I don't really like chicken or soup as a meal.
But I don't care if she makes 5 gallons of this stuff, just between her, her son and me it never makes 3 days.
She uses a whole chicken but uses the breast meat to make her awesome chicken salad to go along with the soup. So don't skimp on the chicken.
If you end up with too much for the soup use the rest for chicken salad.
If life gives you chicken, make soup and salad.
