What is banquet sauce?

"Banquet sauce" is not a commonly recognized culinary term. It's possible you're thinking of a specific sauce that's part of a particular banquet menu, or the term might be a regional or local name for a sauce.

To help me understand what you're looking for, could you provide more information? For example:

* What dish was the sauce served with? Was it a meat dish, a seafood dish, a vegetarian dish?

* What were the ingredients of the sauce? Was it creamy, tomato-based, or something else entirely?

* Where did you hear the term "banquet sauce"? Was it on a menu, in a cookbook, or from someone you know?

With more details, I can try to help you identify the specific sauce you're thinking of.
