I’m thinking the Gruyere popovers would make great sandwiches.
Already have the cheese....just have to add a compatible filling.
Maybe ham salad?
Grind together smoked turkey breast and Major Gray's Chutney. Add chopped green onion and enough mayo to make it stick together.
You can really use any kind of smoked turkey and chutney but the breast was all I could find at the deli and the Major Gray's had just enough heat without overpowering.
It is now "the dish HTB is required to bring to picnics".
