Using hummus instead of butter is a great way to cut calories! One tablespoon of hummus usually contains 25 calories (depending on the recipe). One tablespoon of butter contains 100 calories. I like it as a sandwich spread instead of mayo, too.
I absolutely adore Hummus too! I roll up some cooked turkey and dip it in! Also v good on carrots! I've not started spreading it on bread though - must try that!
