Ingredients
1 1/2 lbs onions, thinly sliced
2 Tbsp olive oil
Fresh thyme
1/2 lb Jack or Gruyere cheese, shredded
1 lb plum tomatoes cut into wedges
1/4 c ripe brine-cured olives, pitted
Salt and pepper to taste
Butter pastry dough
Directions
Preheat oven to 375 degrees.
In a large heavy skillet, cook onions in oil, covered, over moderate heat. Add salt and thyme and stir occasionally until softened, about 20
minutes. Remove lid and cook onions, stirring occasionally, until golden and any liquid evaporates. Remove skillet from heat to cool onions
slightly.
On a lightly floured surface with a floured rolling pin, roll dough into a 14-inch round (about 1/8" thick). Transfer dough to a 12-inch tart
pan with a removable bottom. Unfold dough, easing to fit, and trim overhang to 3/4". Fold overhang toward center and press against side
of pan. Spread onion mixture over dough and top with cheese. Arrange tomato wedges and olives in concentric circles over cheese and season
with salt and pepper.
Bake tart in middle of oven 1 hour, or until pastry is golden, and cool on a rack. Remove rim of pan. Tart can be served warm or room temperature.
