Blend cream cheese, one cup margarine and 2 cups flour; chill. In a skillet, sauté mushrooms and onions in remaining margarine for 3 minutes. Add sour cream, remaining flour, thyme and salt. Cook for several more minutes, stirring occasionally. Divide chilled dough in half; roll out 1/8-inch thick and cut with a 2-1/2" round cutter. Place a heaping 1/4 teaspoon mushroom mixture in center of each circle. Fold over; press edges gently with fingers to seal. Use a spatula to transfer turnovers to a lightly greased baking sheet; press edges with a fork. Brush turnovers with egg white; sprinkle with sesame seed. Bake at 350 degrees for 20 minutes.
