You can make the same thing at home and for a whole lot less money! They are super easy to do as well.
I have checked out sale prices of Hawaiian rolls at Kroger - and have recently found them for 2.99/12 pack. That works out to about .25 each.
Now think about what you have at home. Pulled pork or BBQ pork, shredded Mexican or BBQ chicken, chicken fillets, NO MORE than a slice or two of deli ham or turkey or roast beef (to be like theirs), leftover ham or turkey, mini burgers...………………. There is no end to the type of yummy roll you can make. They offer only 3 kinds!!!!!
The rolls will probably be even cheaper around Thanksgiving and Christmas - so stock up (freeze) and make your own 'sliders' at home any day of the week. You also know what goes on in your kitchen, unlike the environments of the restaurants.
