https://www.bonappetit.com/recipe/vidalia-onion-pissaladiere-pizzas

3 Tbsp. extra-virgin olive oil, plus more for brushing

3 large Vidalia or other sweet onions (about 2 lb. total), thinly sliced

2 tsp. Diamond Crystal or 1¼ tsp. Morton kosher salt

1 lb. store-bought pizza dough, room temperature

All-purpose flour (for surface)

4 oz. oil-packed anchovy fillets, divided

1/2 cup pitted niçoise olives, divided

1 Tbsp. thyme leaves

Step 1

Heat 3 Tbsp. extra-virgin olive oil in a large skillet over medium-high. Add 3 large Vidalia or other sweet onions (about 2 lb. total), thinly sliced, and 2 tsp. Diamond Crystal or 1¼ tsp. Morton kosher salt; cook, stirring often, until onions are softened and translucent, 6–8 minutes. Reduce heat to medium and cook, stirring occasionally and adding a splash of water if onions are sticking to pan, until onions are dark caramel in color and almost blackened around the edges, 20–25 minutes. Let cool.

Step 2

Prepare a grill for medium-high heat. Divide 1 lb. store-bought pizza dough, room temperature, into 2 portions and form into balls. Stretch 1 ball of dough into a 10"–12" round on a lightly floured surface. Brush dough with oil, then invert, oiled side down, onto grill. Grill until large bubbles appear on surface, about 2 minutes. Turn dough over with a pizza peel or large spatula and scatter half of onions evenly over. Top with 2 oz. oil-packed anchovy fillets and ¼ cup pitted niçoise olives. Grill until crust is golden brown underneath, about 2 minutes. Cover and grill until onions are heated through, about 1 minute. Transfer pizza to a cutting board. Repeat with remaining dough and toppings.

Step 3

Scatter 1 Tbsp. thyme leaves over pizzas and cut into wedges.
