Onion sauce is great for most meats and over vegetables. It is a traditional white sauce base with onion and Dijon mustard.

Something else. Stir in the Dijon mustard to taste at the end. - 07 Feb 2011 (Review from Allrecipes UK & Ireland)
This is an excellent recipe. The addition of mustard makes all the difference. I didn't have and Dijon mustard so had to use English instead. It was easy to make and tasted wonderful on a home made toad in the hole. Very moreish? - 21 Feb 2013 (Review from Allrecipes UK & Ireland)
