I'm in Induction too and someone just gave me a great recipe for homemade dressing.

1/2 cup of mayo
1/2 cup of sour cream
1 Tablespoon yellow mustard
1 Tablespoon vinegar (I used plain white vinegar)
1 teaspoon Worchester Sauce
Salt and pepper

Mix together and put in a container to leave in the fridge. It kind of taste like a honey mustard dressing. Instead of just pouring over the top of my salad, I mix it in really well with my lettuce. I don't think you use as much that way.
