Recipe For Ranch Italian Dressing They Have A House Salad Dressing At Just About Every Italian Restaurant I Have Been To. Anyone Know What It Is

They have a house salad dressing at just about every Italian restaurant I have been to. Anyone know what it is - recipe for ranch italian dressing

It is red. I have a bitter taste, but a little sweet. Some of those Italian restaurants call the Italian house dressing, and some call Red Dressing. Has anyone a recipe for something similar? I always ate ranch dressing and not a fan of someone else, but I like the clothes.
