This can be served as a dinner or an appetizer. It is positively amazing. This is my own creation inspired by my favorite dish at a local NJ restaurant. I hope you like it as much as I do.

I have made this several times, and didn't change a thing. My husband loves it so much he says it is better than restaurants!

Wonderful! I, too, seared whole tuna steaks on the grill to a medium doneness and they were lovely. The mustard sauce is fantastic and quite plentiful. We even had our leftovers cold, and the tuna and sauce were still great. I can see using this mustard sauce on a myriad of dishes as well. Thanks for posting this.

This was wonderful! Especially the sauce was fantastic, and I agree, it would be superb with crab cakes. Made with reduced fat sour cream and mayo. Made for ZWT5
