Measurements depend on size of ham slices and personal taste:
sliced deli ham (about as thick as Oscar Mayer packaged ham)
cream cheese, softened
dash of Worcestershire sauce
dash of garlic powder
dash of onion powder (or minced chives)
chopped parsley (for color if chives aren’t used)
Blend cream cheese with all other ingredients except ham, adjusting amounts to taste. Spread a thin layer of cheese mixture onto each ham slice. Roll up jellyroll-style, cover, and place in freezer until firm (even a couple of days in advance is okay).
At least a few hours (or the night before) before serving, remove from freezer and allow to soften slightly for a few minutes. Use a sharp knife to cut each roll into slices about 3/4 inch thick. Spear each slice with a toothpick to secure, cover, and refrigerate. Serve when completely thawed.
