Patsy's Breakfast Tarts
Meanwhile, cook the bacon in a medium skillet over medium heat, turning, until crisp, 8 to 10 minutes. Transfer to paper towels to drain, then crumble.
Let the tart shells cool slightly on the baking sheets. If the centers are very puffy, prick with a fork to deflate. Sprinkle evenly with the havarti and parmesan. Make a shallow well in the cheese in the center of each tart and crack an egg into each; season with salt and pepper. Top with the bacon, then return to the oven and bake until the egg whites are set, 10 to 15 minutes. Top with chives (or herb of your choice).
