My mother used to make little ham party rolls for special occasions. It's a somewhat trashy recipe, but it tastes good and veganizes easily.
1 tray of dinner rolls (storebought or make your own)
Approx 1 cup shredded vegan cheese (Cheddar Daiya in our case)
1 package of vegan ham-style slices (or make your own and slice thin)
1/4 c vegan margarine
1 T Dijon mustard
1 t vegan worcestershire sauce
1 T poppy seeds
Slice the dinner rolls in half. Mix the margarine, mustard, worcestershire, and poppy seeds. Spread this mixture on the rolls. Layer your vegan ham and cheese on the rolls, and wrap them in foil. Bake at 350 F until everything is hot and melty.
