Super Simple Tomato Tart

Name: Super Simple Tomato Tart
Ingredients: 1. One 10-inch sheet frozen puff pastry, such as Pepperidge Farm. They come two to a package, so just pull one out and let it thaw in the refrigerator for a few hours (overnight is best if you can manage it).; 2. 3-4 Roma tomatoes (any tomato will do but you can find decent Roma's even in the dead of winter) thinly sliced; 3. 1 clove of garlic finely minced (or grated on a microplane); 4. 2-3 (truly use as much or as little as you like) tablespoons fresh basil, finely chopped and divided; 5. 3 tablespoons (approx, just eyeball it) olive oil (plus a little more to grease the pan); 6. 2 tablespoons crumbled feta cheese (I like the tomato basil flavor but you can use whatever you like); 7. 1 egg, cracked into a small bowl and well-whisked together (say that 3 times fast); 8. salt and pepper to taste
