Directions

1. Combine flour, 1 teaspoon salt, and 1 tablespoon thyme in a food processor. Add butter, and process until mixture resembles coarse meal, about 10 minutes. With the motor running, slowly pour in ice water until mixture holds together when squeezed. Wrap in plastic, and press into a flat disk. Chill until firm.
2. Heat oil in a large saute pan over medium heat. Add onions, and cook until soft. Add cabbage; reduce heat. Add 1/2 cup water, 2 tablespoons thyme, vinegar, sugar, and salt and pepper to taste. Cover; cook 10 minutes. Uncover, turn heat up, and cook until liquid is gone.
3. Heat oven to 425 degrees. Quarter dough, and roll into 5-inch circles. Fit into 4-inch flan rings. Add filling, and scatter cheese on top. Fold over pastry edges. Chill until firm. Bake 15 to 20 minutes; serve hot.
