I make them in mini muffin trays, I cut each slice of puff pastry into 9 squares, or I cut in rounds using a tupperware cutter. I use tinned corn, kraft block cheese (the stuff you get thats not in the cold section... I only use this cheese for 2 recipes as I am not a fan of processed cheese but I just can't get the same taste with fresh cheese!) chives/spring onion, cream, milk and egg. I'll find my exact recipe if you're interested. You can add diced bacon if you like. I also freeze them for DD for school and she loves them!
