Just Can't Get Enough

People requested this so here it is. The credit for this goes to Margie, who, though I doubt she came up with the recipe, first coined the phrase, "it tastes a lot better than it sounds."
Tomato Pie
crust: 1 3/4 c flour, 1/4 tsp. salt, 1/2 c butter, 1 egg
Stir together flour and salt. Add butter and blend to meal consistency. Add egg. Press dough into 11-inch pie plate. Chill for 30 minutes.
pie: 1/4 c Dijon mustard, 1/4lb gruyere cheese (grated), 3 large (1 1/2lbs) tomatoes (sliced), 2 Tbsp minced fresh parsley, 1 Tbsp minced fresh oregano or thyme, 1 tsp. garlic (minced), 1/4 c olive oil.
Spread mustard over chilled pie shell and sprinkle with cheese. Arrange the tomato slices over the cheese. Sprinkle with herbs, garlic, and oil. Bake in 400° oven for 40 minutes.
comments: There's just no way to make this taste bad. I've been using prepared crusts and substituting Swiss cheese for gruyere. I've also made it in the winter with all dried herbs. It's funny because I hate mustard on sandwiches, but I love it in this recipe.
