1. Let puff pastry thaw at room temperature until it can be unfolded without breaking (the pastry should be cool but pliable).
2. Preheat oven to 425°. 
3. Unfold pastry sheet onto a parchment-lined baking sheet. Using a fork, pierce pastry all over, leaving a ½" border. 
4. Bake puff pastry in preheated oven for 10 min. 
5. Remove from oven; let cool for 5 min. 
6. In a small mixing bowl, whisk 1 egg. Brush egg wash over border of pastry; sprinkle with bagel seasoning.
7. Spread mustard evenly over pastry, avoiding the border.
8. Arrange ham evenly over pastry, leaving 5 round wells for the eggs. Crack 1 egg into each well; sprinkle with cheese. 
9. Return to oven; bake until eggs are cooked to desired doneness (about 12 min. for runny yolks). 
10. Remove from oven; let cool for 5 min.
11. Season tart with salt and pepper; top with desired garnishes. Serve immediately.

Tasty Tips:

• No leftover ham? Find ham steaks in the Meat Department or ham sliced to order at the Deli Service Counter. 
• Any variety of shredded cheese will work well in this recipe. 
• If the pastry browns before the eggs are done, cover the exposed crust with strips of aluminum foil to prevent it from getting too dark.
