I'm willing to bet that many of us have made an Italian dressing from a packaged seasoning mix. It's a staple in many American grocery stores and a convenience food, no doubt.
Add the powder dressing mix to oil and vinegar, and in some cases shake it up in a glass bottle that comes with the seasoning mix, and you get a yellow dressing that's flecked with various red, black and green herb and pepper bits.
Sounding familiar? Bringing back some memories of either loving (or loathing) salad in years past?
I thought so... and I know I've personally poured it over plenty bowls of green salads made with romaine or Iceberg lettuce, tomatoes, onions, cucumbers, and sometimes black olives growing up.
