Mexican Mini Cheesecake Appetizers

These little cheesecakes are a product of my own imagination.  I am still not completely happy with the crust.  They don't really need one because the filling holds together nicely.  I tried crushed corn chips first and that was a complete disaster.  The little guys in the picture have a cracker crumb crust.  I thought about putting a little round of soft bread under the filling, letting it soak up the cheese mixture as it baked, but didn't get around to trying that.  An old fashioned pastry crust would work, but that was more work than I was willing to put forth at the time.
