Ingredients

1/3 recipe Basic Pizza Dough, or 3/4 pound store-bought dough 

1 to 2 small potatoes, peeled and thinly sliced 

1/4 cup black nicoise olives, pitted 

Extra-virgin olive oil 

Coarse salt 

3 to 4 ounces jarred oilpacked tuna (about 1/2 jar) 

2 ounces haricots verts, blanched and sliced in half on the bias 

1 small red tomato, cut into thin wedges 

1 handful baby arugula 

1/4 small red onion, halved and thinly sliced 

2 teaspoons red-wine vinegar 

Preparation

Preheat oven to 475 degrees. Form dough (as directed in Basic Pizza Dough recipe) in a 9-by-13-inch rimmed baking sheet. Arrange half of potato slices on top half of dough, the rest on bottom half, covering entirely; press into dough. Add olives, pressing into dough. Brush with oil and sprinkle with salt.

Bake until cooked through and crust is golden on edges and bottom, about 18 minutes.

Using a metal spatula, slide pie onto a cutting board. Artfully arrange tuna and remaining vegetables on top; sprinkle with vinegar and drizzle with more oil. (Alternatively, toss these ingredients together in a bowl, then top pie with salad.) Slice into 6 pieces and serve.
