I used ½ a bag of Costco bacon crumbles. You can bake and crumble your own bacon but this was much easier! Just make sure you use 100% real bacon crumbles. You can use either cream cheese or mayo. I prefer the taste of cream cheese! I have baked these with the pastry cups frozen and it works too. Just bake a little longer if needed. I used original rotel diced tomatoes. If you don't like things really spicy, use the mild flavor. And if you like them really hot, there is always the hot option :)
