Don't tell your mom, but you've found your own special recipe. This version has a little more zing, a touch of mustard and a whole new better-for-you approach to barbecue.
Prepare this salad ahead of time and serve chilled, if you like. Spoon into avocado halves and serve with whole wheat crackers for a refreshing lunch or dinner.
This side-dish salad uses fat-free mayonnaise in the dressing so it's much lower in fat than a regular Caesar salad. Portobello mushrooms add a meaty flavor.
