It's nothing fancy. Olive oil, squeezed lemon, Dijon mustard, fine chopped green or cooking onion, garlic and red pepper spice, garlic plus powder, black pepper from a mill, and flaked vegetable spice seasoning... whip with a whisk, add a couple of drops of Worcestershire if you want, and let sit five minutes. Don't overdo the Dijon... I use two fork dollops. Chicken is grilled with the same seasonings, plus some Montreal chicken seasoning. I sometimes use a smoked paprika and onion spice, but it can be a little much... can almost make the chicken taste fishy which is fine sometimes. Don't ask me about measurements. I make it in the bottom of the salad bowl each time, and I just splash in the amounts I think I need.
I also add both fresh shredded parmesan and shredded old cheddar... lots of it.
That's it.
