Bake the pie crust according to recipe or package directions only until just lightly brown, for about 15 to 17 minutes. Then remove from the oven and brush the pie all over with a lightly beaten egg white and set aside.
Preheat the oven to 375 degrees.
Rinse the onions several times to make sure they are free of grit. Drain well and dab with paper towels. Heat the oil in a medium-size skillet. Add the onions, basil or thyme, salt, black pepper, nutmeg and cayenne or hot pepper sauce, and sauté over medium-low heat for 3 or 4 minutes, stirring, just until the onions are limp but not browned. Stir in the flour and sauté 2 minutes longer, stirring. Remove the skillet from the heat.
