Fennel, Radish and Cucumber Salad with Tuna Dressing (Tonnato)

This dressing is your basic Caesar with tuna substituting for anchovies. It is very simple and very versatile. We served it drizzled over radishes, cucumbers and fennel. But I challenge you to find a vegetable this dressing doesn't go well with. It's great on boiled beets, raw tomatoes, green beans… I could go on and on but have already exhausted my welcome in this sentence. You get the point, eat more vegetables.
