Heat walnuts in a small nonstick skillet over medium-low heat, stirring often, 5 to 6 minutes or until lightly toasted and fragrant.
Remove rolls from packages. (Do not separate rolls.) Cut rolls in half horizontally, creating 1 top and 1 bottom per package. Spread preserves on cut sides of top of rolls; sprinkle with walnuts. Spread mustard-mayonnaise blend on cut sides of bottom of rolls; top with roast beef and cheese. Sprinkle with salt and pepper, if desired. Cover with top halves of rolls, preserves sides down, and wrap in aluminum foil.
Bake at 325° for 30 minutes or until cheese is melted. Slice into individual sandwiches. Serve immediately.
Note: To make ahead, prepare recipe as directed through Step 3, and freeze up to 1 month. Thaw overnight in refrigerator, and bake as directed in Step For testing purposes only, we used Rainbo Dinner Time Rolls, Hellmann's Dijonnaise Creamy Dijon Mustard, and Boar's Head Londonport Roast Beef.
Wow, what a great sandwich! I made them for a party and they were a huge hit! I did not use dinner rolls that were attached to each other. I used a more substantial bread. The sandwiches still turned out wonderful. The combination of the sweet peach preserves and the mustard/mayo mixture worked perfectly. Also, I did not have walnuts, so I used toasted pecans and I wished I would have sprinkled more on each sandwich. They added a great crunch. I can't wait to make these again!!!
Loved this recipe! I made it without the nuts and with homemade peach preserves. I used to a bread knife to cut the bread which made it slightly easier but the bread is really soft and hard to cut. Everyone LOVED this recipe! I'll definitely add this to my book of recipes.
Made and froze these ahead of time for Christmas. Just heated them up and the extended family lapped them up. Even defrosted, you may need to cook a bit longer as the preserves can make the rolls a bit soggy. But they were unanimously voted 'scrumptious!'
This was DELICIOUS. I recommend using a chunky peach preserve and definitely toasting the walnuts pre-assembly - I didn't toast mine and they added no flavor. I didn't have any havarti on hand so I used swiss, and they were out of this world! I can't wait to make these again.
was hesitant with the walnut/beef/peach combo. So glad I took the plunge! So good!! Reminiscent of the little ham sandwiches everyone serves but a nice twist. Served at Christmas open house and people loved them.
I had a party for my son after he moved into his new home and made these.....needless to say there weren't any left over! Alot of 20ish young people there and they ate them up! Very easy to prepare! We'll definitely make these again for a wedding shower coming up.
