With the rack in the middle position, preheat the oven to 180 °C (350 °F).
In a food processor, combine the cream cheese and mayonnaise until the mixture is smooth. Add the remaining ingredients and pulse a few seconds at a time, until the mixture has a crumbly texture, to taste.
Spoon into an oven-safe serving dish. Bake for 20 minutes or until the dip is golden brown.
Serve immediately with raw vegetables, croutons and root vegetable chips.
