If you like strong pungent flavors, then this tart is for you. As far as the anchovies, don't let them turn you away from this tart. The anchovies veritably melt into the dish and there is just a hint, JUST A HINT, to add depth to the topping. I sneak in anchovies in many of my seafood stews and no one is the wiser. I remember my husband and I ordering pizza at Lake Maggiore in Italy. I ordered a Mediterranean pizza which was simply pizza dough, tomato sauce anchovies. He couldn't watch me eat it. But for me it was yummy. And so is this. From Fine Cooking magazine: 
1 lb. homemade or store-bought pizza dough, thawed if frozen
1/4 cup extra-virgin olive oil
2 lb. yellow onions (about 4 medium), halved through the root and thinly sliced crosswise (see below)
Kosher salt
1 large clove garlic, minced
4 anchovy fillets, rinsed, patted dry, and chopped
1 Tbs. chopped fresh thyme
All-purpose flour, as needed
1 Tbs. capers, rinsed and coarsely chopped
15 Kalamata or Niçoise olives, pitted and slivered
Position a rack in the center of the oven, set a pizza stone on the rack, and heat the oven to 450°F. (If you don’t have a pizza stone, set a rimmed baking sheet upside down on the rack to serve as a baking platform.) Let the pizza dough come to room temperature.
Meanwhile, heat 1 Tbs. of the olive oil in a 12-inch skillet over medium-high heat until shimmering hot. Add the onions and a generous pinch of salt. Cook, stirring, until the onions are golden and softened, about 10 minutes. Make a space in the skillet and add the minced garlic. Let sizzle until fragrant, then stir into the onions and cook, stirring occasionally, to blend the flavors, about 2 minutes. Season to taste with salt. Remove from the heat.
In a 1-quart saucepan over low heat, heat the remaining 3 Tbs. oil with the anchovies and thyme. Cook, stirring and breaking up the anchovies with a wooden spatula until they’re dissolved, about 1-1/2 minutes. Remove from the heat.
Cut the pizza dough in half. Working with half at a time on a lightly floured surface, use your fingers to flatten and stretch it. Then, using a lightly floured rolling pin, roll the dough into a 9x13-inch rectangle (rounded corners are fine). If at any time the dough begins to shrink back, let it rest for 10 minutes and then roll again. Transfer the dough to a piece of parchment. Brush the dough with half of the anchovy oil, then spread with half of the onion mixture. Sprinkle half of the capers and olives evenly on top. Slide the parchment and dough onto a pizza peel (or an inverted baking sheet), then slide the parchment and dough onto the hot pizza stone (or baking sheet). Bake until golden-brown, 10 to 12 minutes. Prepare the second tart while the first cooks.
Remove the first tart from the oven and transfer to a cutting board. Bake the second tart. Let the tarts cool for at least 5 minutes before slicing and serving.
