I originally made a version of this recipe from my beloved Beat This cookbook, and while I really liked it there were some issues. For one thing, dear Ann Hodgman, the author, has you make your own pesto and then drain it in a sieve to get as much of the oil out as you can–so you put the oil in, and then you take the oil out. You can certainly buy pre-made pesto, as I do, but be sure you buy it from Costco or some such. Regular grocery stores sell it, but it comes in small jars with big prices. She called for sun-dried tomatoes for the tomato layer, but she specified that they be dry-packed, not oil-packed, which are hard to find. The tomatoes were to be diced and scattered across the cream-cheese layer, which meant that you wouldn’t necessarily get any tomato in a small dab on a cracker. It never occurred to me that I could make it any differently, so I made it Ann’s way and people really liked it. Later on I ran into the version I’m posting here. and because the layers all have some cream cheese in them and are mixed in a food processor they’re pretty smooth. Then, I realized that the sun-dried tomatoes aren’t really necessary because they’re going to get pureed anyway; you can just use tomato paste. What you really want is the color and the taste.
