I’ve done roll ups as Deb mentioned with tortillas and cream cheese but I use turkey, cranberry and sprouts.
You can also do ham roll ups with cream cheese and then you add gherkin pickle strips down the middle or green onion slivers then after chilled, cut them in bite size pieces.
I just made 98 mini quiche for a baby shower and if you have a small muffin pan, they’re easy too. You can concoct any kind of filling...I made mushroom spinach and also bacon and green onion.
