As far as classic sandwiches go, ham and cheese has to be right up there with peanut butter and jelly. Part of its appeal is its adaptability. Here, French ham mixes with nutty Gruyere and mild hard-cooked eggs. The sandwich gets its crunch from a handful of frisee and a layer of dill pickles.
The uniform heat of a panini press gives these vegetable sandwiches just the right crispness. But they can easily be made without a press: Heat the panini in a heavy skillet (preferably cast iron) over medium heat, and set another heavy skillet on top of them as they cook.
By way of France, in this Riviera-inspired sandwich stuffer, a simple vinaigrette marries potatoes, green beans, Nicoise olives, tomatoes, and tuna. When only a baguette will do for a sandwich, scoop out the interior; you'll cut back on refined carbohydrates and calories.
