How to make ham sliders

Use an electric knife to cut the rolls in half horizontally!

Make ahead of time and pour the sauce on right before baking.

I usually use a 9×13 plus a 8×8 pan.

The secret is the pesto!

  1. Thank you for such an amazing recipe. I wonder what other sauces might be good. For example, I’m a mayonnaise girl, always have been and always will be :) I wonder how these sliders would be with either just plain mayonnaise or a jazzed up mayonnaise would be. Any suggestions or thoughts.
