1Preheat your oven to 375°F (190°C).
In a large bowl, whisk together the eggs, milk, and yogurt until well combined.
Add the diced ham, sliced tomatoes, and shredded cheese to the egg mixture. Stir to combine.
Pour the mixture into the pie crust, spreading it evenly.
Place the quiche in the preheated oven and bake for 35-40 minutes, or until the center is set and the top is golden brown.
Remove from the oven and let it cool for a few minutes before slicing.
Serve warm and enjoy your Tomato and Ham Quiche.
