I saw this on one of Giada's shows and thought it would be good over pasta instead of served on bruschetta. This was really very good, and easy enough for a weeknight meal. One batch of the topping covers half a pound of pasta very nicely.
Other changes I made include omitting the tarragon (don't like the flavor), using a can of drained diced tomatoes instead of the Romas, and substituting the new Philadelphia Cooking Creme for the mascarpone cheese.
