Preheat oven to 375°F. In a bowl, mix until smooth the cream cheese, cheddar cheese, and hot sauce. 

In a greased mini muffin pan, add puff pastry circles, and form circles like small cups in each muffin hole. 

Add cream cheese filling mixture into puff pastry cups, fill halfway up, placing a meatball on top of each cup, brush puff pastry with egg wash, then top each pastry cup with blue cheese crumbles. 

Place muffin pan in the oven, bake for 10- 15 minutes or until golden brown. Remove from the oven and serve immediately.
