This recipe came from Delish. While I may not add mushrooms next time, it’s a pretty good Caesar dressing. 

Caesar Dressing

1 hard-cooked egg
2 tablespoons olive oil
1 1/2 tablespoons white wine vinegar
minced garlic, salt and pepper to taste
1/2 teaspoon anchovy paste, optional

Combine ingredients in small food processor. Toss with Romaine, Parmesan cheese and croutons. Add fresh or cooked mushrooms, or maybe even chicken or shrimp, whatever you’d like. This was enough dressing for two large servings.
