I found it somewhat bland and not at all worth the effort (including clean-up) involved.
Delicious and easy. I used a dark mustard so the sauce was a bit darker than if I had used a yellow mustard. I served this as Saturday dinner with a bratwurst on the other half of the bun Thanks Sharon love the recipe
Mmmmmm, yummy! I love the little bite of the mustard powder ... be sure to heed the "firm" tomatoes suggestion, too. I can't wait to make this with some of my fresh heirloom tomatoes from the garden this summer! This is almost better than grilled cheese and tomato soup! Thanks so much for a winner, something a little different!
This was great. Loved each and every bite. Will be making this again.
