So my fiancee and I were enjoying a relatively easy going dinner at Carrabba's in Brookfield, WI last night and she just had a side Caesar salad and minestrone soup. When the minestrone soup came, it had a rather light broth with it instead of the traditional tomato broth or vegetable broth with tomatoes. When I asked the waitress if the soup was indeed minestrone since they do have a spicy chicken soup with vegetables on the menu. She said, "Yeah that's the minestrone soup, we just don't dye our broth". I didn't know most restaurants who use tomatoes in their broth use red dye in their soup, I'm surprised I've never seen it on the recipes for it.
