I like the kale and non-iceberg lettuce mixes. Some days when I'm dealing with various physical and mental issues, eating healthy is not on my easily done list. But you grab one of those bags and some sort of protein like the crab, or hardboiled egg, leftover rotisserie chicken, whatever and it's easy to make and clean up and lots of different varieties.
Watching my carbs, I've found the Ken's dressings to be within my tolerances.
